Auto merge of #9541 - Alexendoo:declare-proc-macro, r=flip1995

Browse source 
Generate lint categories and explanations with `declare_clippy_lint`

This means contributors will no longer have to run `cargo dev update_lints` after changing a lints documentation or its category, which may also mean fewer merge conflicts in general

It works by swapping `declare_clippy_lint` out for a `proc_macro` of the same name. The proc macro emits a `LintInfo` alongside the generated `Lint` which are gathered into `declared_lint::LINTS`. The categories/explanations are then read from `declared_lint::LINTS` at runtime

The removal of `src/docs` is split into a separate commit to be more easily ignored

It is slightly slower though, adding a bit under a second to build time. Less noticeable in full builds or with a slower linker (benchmark uses mold)

```bash
hyperfine --warmup 2 \
    --parameter-list commit "declare-proc-macro,master" \
    --command-name "{commit}" \
    --setup "git checkout {commit}" \
    --prepare "touch clippy_lints/src/lib.rs" \
    "cargo build"
```
```
Benchmark 1: declare-proc-macro
  Time (mean ± σ):     10.731 s ±  0.154 s    [User: 7.739 s, System: 1.791 s]
  Range (min … max):   10.598 s … 11.125 s    10 runs

Benchmark 2: master
  Time (mean ± σ):      9.422 s ±  0.094 s    [User: 7.183 s, System: 1.732 s]
  Range (min … max):    9.287 s …  9.624 s    10 runs

Summary
  'master' ran
    1.14 ± 0.02 times faster than 'declare-proc-macro'

### What it does
Checks for comparisons where one side of the relation is
either the minimum or maximum value for its type and warns if it involves a
case that is always true or always false. Only integer and boolean types are
checked.
### Why is this bad?
An expression like `min <= x` may misleadingly imply
that it is possible for `x` to be less than the minimum. Expressions like
`max < x` are probably mistakes.
### Known problems
For `usize` the size of the current compile target will
be assumed (e.g., 64 bits on 64 bit systems). This means code that uses such
a comparison to detect target pointer width will trigger this lint. One can
use `mem::sizeof` and compare its value or conditional compilation
attributes
like `#[cfg(target_pointer_width = "64")] ..` instead.
### Example
```
let vec: Vec<isize> = Vec::new();
if vec.len() <= 0 {}
if 100 > i32::MAX {}
```

### What it does
Finds items imported through `alloc` when available through `core`.
### Why is this bad?
Crates which have `no_std` compatibility and may optionally require alloc may wish to ensure types are
imported from core to ensure disabling `alloc` does not cause the crate to fail to compile. This lint
is also useful for crates migrating to become `no_std` compatible.
### Example
```
use alloc::slice::from_ref;
```
Use instead:
```
use core::slice::from_ref;
```

### What it does
Checks for floating point literals that approximate
constants which are defined in
[`std::f32::consts`](https://doc.rust-lang.org/stable/std/f32/consts/#constants)
or
[`std::f64::consts`](https://doc.rust-lang.org/stable/std/f64/consts/#constants),

Usually, the definition in the standard library is more
precise than what people come up with. If you find that your definition is
actually more precise, please [file a Rust
issue](https://github.com/rust-lang/rust/issues).
### Example

let x = 3.14;

```
let x = std::f32::consts::PI;
let y = std::f64::consts::FRAC_1_PI;

### What it does
Checks any kind of arithmetic operation of any type.
Operators like `+`, `-`, `*` or `<<` are usually capable of overflowing according to the [Rust
Reference](https://doc.rust-lang.org/reference/expressions/operator-expr.html#overflow),
or can panic (`/`, `%`).
Known safe built-in types like `Wrapping` or `Saturating`, floats, operations in constant
environments, allowed types and non-constant operations that won't overflow are ignored.
### Why is this bad?
For integers, overflow will trigger a panic in debug builds or wrap the result in
release mode; division by zero will cause a panic in either mode. As a result, it is
desirable to explicitly call checked, wrapping or saturating arithmetic methods.
#### Example
```
// `n` can be any number, including `i32::MAX`.
fn foo(n: i32) -> i32 {
n + 1
}
```
Third-party types can also overflow or present unwanted side-effects.
#### Example
```
use rust_decimal::Decimal;
let _n = Decimal::MAX + Decimal::MAX;
```
### Allowed types
Custom allowed types can be specified through the "arithmetic-side-effects-allowed" filter.

View file

@ -1,32 +0,0 @@
### What it does
Checks for usage of `as` conversions.
Note that this lint is specialized in linting *every single* use of `as`
regardless of whether good alternatives exist or not.
If you want more precise lints for `as`, please consider using these separate lints:
`unnecessary_cast`, `cast_lossless/cast_possible_truncation/cast_possible_wrap/cast_precision_loss/cast_sign_loss`,
`fn_to_numeric_cast(_with_truncation)`, `char_lit_as_u8`, `ref_to_mut` and `ptr_as_ptr`.
There is a good explanation the reason why this lint should work in this way and how it is useful
[in this issue](https://github.com/rust-lang/rust-clippy/issues/5122).
### Why is this bad?
`as` conversions will perform many kinds of
conversions, including silently lossy conversions and dangerous coercions.
There are cases when it makes sense to use `as`, so the lint is
Allow by default.
### Example
```
let a: u32;
...
f(a as u16);
```
Use instead:
```
f(a.try_into()?);
// or
f(a.try_into().expect("Unexpected u16 overflow in f"));
```

@ -1,19 +0,0 @@
### What it does
Checks for the result of a `&self`-taking `as_ptr` being cast to a mutable pointer
### Why is this bad?
Since `as_ptr` takes a `&self`, the pointer won't have write permissions unless interior
mutability is used, making it unlikely that having it as a mutable pointer is correct.
### Example
```
let string = String::with_capacity(1);
let ptr = string.as_ptr() as *mut u8;
unsafe { ptr.write(4) }; // UNDEFINED BEHAVIOUR
```
Use instead:
```
let mut string = String::with_capacity(1);
let ptr = string.as_mut_ptr();
unsafe { ptr.write(4) };

### What it does
Check for the usage of `as _` conversion using inferred type.
### Why is this bad?
The conversion might include lossy conversion and dangerous cast that might go
undetected due to the type being inferred.
The lint is allowed by default as using `_` is less wordy than always specifying the type.
### Example
```
fn foo(n: usize) {}
let n: u16 = 256;
foo(n as _);
```
Use instead:
```
fn foo(n: usize) {}

### What it does
Checks for calls to await while holding a non-async-aware MutexGuard.
### Why is this bad?
The Mutex types found in std::sync and parking_lot
are not designed to operate in an async context across await points.
There are two potential solutions. One is to use an async-aware Mutex
type. Many asynchronous foundation crates provide such a Mutex type. The
other solution is to ensure the mutex is unlocked before calling await,
either by introducing a scope or an explicit call to Drop::drop.
### Known problems
Will report false positive for explicitly dropped guards
([#6446](https://github.com/rust-lang/rust-clippy/issues/6446)). A workaround for this is
to wrap the `.lock()` call in a block instead of explicitly dropping the guard.
### Example
```
async fn foo(x: &Mutex<u32>) {
let mut guard = x.lock().unwrap();
*guard += 1;
baz().await;
}
async fn bar(x: &Mutex<u32>) {
let mut guard = x.lock().unwrap();
*guard += 1;
drop(guard); // explicit drop
baz().await;
}
```
Use instead:
```
async fn foo(x: &Mutex<u32>) {
{
let mut guard = x.lock().unwrap();
*guard += 1;
}
baz().await;
}
async fn bar(x: &Mutex<u32>) {
{
let mut guard = x.lock().unwrap();
*guard += 1;
} // guard dropped here at end of scope
baz().await;

### What it does
Checks for calls to await while holding a `RefCell` `Ref` or `RefMut`.
### Why is this bad?
`RefCell` refs only check for exclusive mutable access
at runtime. Holding onto a `RefCell` ref across an `await` suspension point
risks panics from a mutable ref shared while other refs are outstanding.
### Known problems
Will report false positive for explicitly dropped refs
([#6353](https://github.com/rust-lang/rust-clippy/issues/6353)). A workaround for this is
to wrap the `.borrow[_mut]()` call in a block instead of explicitly dropping the ref.
### Example
```
async fn foo(x: &RefCell<u32>) {
let mut y = x.borrow_mut();
*y += 1;
baz().await;
}
async fn bar(x: &RefCell<u32>) {
let mut y = x.borrow_mut();
*y += 1;
drop(y); // explicit drop

### Why is this bad?
If the bits that the comparison cares about are always
set to zero or one by the bit mask, the comparison is constant `true` or
`false` (depending on mask, compared value, and operators).
So the code is actively misleading, and the only reason someone would write
this intentionally is to win an underhanded Rust contest or create a
test-case for this lint.
### Example
```
if (x & 1 == 2) { }
```

### Why is this bad?
Readability, this can be written more concisely as

### What it does
Checks if `const` items which is interior mutable (e.g.,
contains a `Cell`, `Mutex`, `AtomicXxxx`, etc.) has been borrowed directly.
### Why is this bad?
Consts are copied everywhere they are referenced, i.e.,
every time you refer to the const a fresh instance of the `Cell` or `Mutex`
or `AtomicXxxx` will be created, which defeats the whole purpose of using
these types in the first place.
The `const` value should be stored inside a `static` item.
### Known problems
When an enum has variants with interior mutability, use of its non
interior mutable variants can generate false positives. See issue
[#3962](https://github.com/rust-lang/rust-clippy/issues/3962)
Types that have underlying or potential interior mutability trigger the lint whether
the interior mutable field is used or not. See issues
[#5812](https://github.com/rust-lang/rust-clippy/issues/5812) and
[#3825](https://github.com/rust-lang/rust-clippy/issues/3825)
### Example
```
use std::sync::atomic::{AtomicUsize, Ordering::SeqCst};
const CONST_ATOM: AtomicUsize = AtomicUsize::new(12);
CONST_ATOM.store(6, SeqCst); // the content of the atomic is unchanged
assert_eq!(CONST_ATOM.load(SeqCst), 12); // because the CONST_ATOM in these lines are distinct

Using `&T` defines a concrete type for the parameter and generalizes the function, this would also
auto-deref to `&T` at the function call site if passed a `&Box<T>`.

### What it does
Checks for casts between numerical types that may
be replaced by safe conversion functions.
### Why is this bad?
Rust's `as` keyword will perform many kinds of
conversions, including silently lossy conversions. Conversion functions such
as `i32::from` will only perform lossless conversions. Using the conversion
functions prevents conversions from turning into silent lossy conversions if
the types of the input expressions ever change, and make it easier for
people reading the code to know that the conversion is lossless.
### Example
```
fn as_u64(x: u8) -> u64 {
x as u64
}

Using `::from` would look like this:

fn as_u64(x: u8) -> u64 {
u64::from(x)

### What it does
Checks for casts from an unsigned type to a signed type of
the same size. Performing such a cast is a 'no-op' for the compiler,
i.e., nothing is changed at the bit level, and the binary representation of
the value is reinterpreted. This can cause wrapping if the value is too big
for the target signed type. However, the cast works as defined, so this lint
is `Allow` by default.
### Why is this bad?
While such a cast is not bad in itself, the results can
be surprising when this is not the intended behavior, as demonstrated by the
example below.

or any 64-bit integer to `f64`.
### Why is this bad?
It's not bad at all. But in some applications it can be

those places in the code.

View file

@ -1,38 +0,0 @@
### What it does
Checks for `as` casts between raw pointers to slices with differently sized elements.
### Why is this bad?
The produced raw pointer to a slice does not update its length metadata. The produced
pointer will point to a different number of bytes than the original pointer because the
length metadata of a raw slice pointer is in elements rather than bytes.
Producing a slice reference from the raw pointer will either create a slice with
less data (which can be surprising) or create a slice with more data and cause Undefined Behavior.
### Example
// Missing data
```
let a = [1_i32, 2, 3, 4];
let p = &a as *const [i32] as *const [u8];
unsafe {
println!("{:?}", &*p);

let a = [1_u8, 2, 3, 4];
let p = &a as *const [u8] as *const [u32];
unsafe {
println!("{:?}", &*p);

Instead use `ptr::slice_from_raw_parts` to construct a slice from a data pointer and the correct length
```
let a = [1_i32, 2, 3, 4];
let old_ptr = &a as *const [i32];
// The data pointer is cast to a pointer to the target `u8` not `[u8]`
// The length comes from the known length of 4 i32s times the 4 bytes per i32
let new_ptr = core::ptr::slice_from_raw_parts(old_ptr as *const u8, 16);

### What it does
Checks for usage of `.clone()` on a `Copy` type.

### What it does
Checks for usage of `.clone()` on a ref-counted pointer,
(`Rc`, `Arc`, `rc::Weak`, or `sync::Weak`), and suggests calling Clone via unified
function syntax instead (e.g., `Rc::clone(foo)`).
### Why is this bad?
Calling '.clone()' on an Rc, Arc, or Weak
can obscure the fact that only the pointer is being cloned, not the underlying
data.
### Example
```
let x = Rc::new(1);
x.clone();
```
Use instead:
```
Rc::clone(&x);

### What it does
Finds nested `match` or `if let` expressions where the patterns may be "collapsed" together

Note that this lint is not intended to find _all_ cases where nested match patterns can be merged, but only
cases where merging would most likely make the code more readable.

It is unnecessarily verbose and complex.
### Example
```
fn func(opt: Option<Result<u64, String>>) {
let n = match opt {

not inlining the call to cmp. See issue [#5354](https://github.com/rust-lang/rust-clippy/issues/5354)

### What it does
Checks for comparing to an empty slice such as `""` or `[]`,

### Why is this bad?
Some structures can answer `.is_empty()` much faster
than checking for equality. So it is good to get into the habit of using
`.is_empty()`, and having it is cheap.
Besides, it makes the intent clearer than a manual comparison in some contexts.
### Example
```
if s == "" {
..

if arr == [] {

### What it does
Checks for use of `crate` as opposed to `$crate` in a macro definition.
### Why is this bad?
`crate` refers to the macro call's crate, whereas `$crate` refers to the macro definition's
crate. Rarely is the former intended. See:
https://doc.rust-lang.org/reference/macros-by-example.html#hygiene
### Example
```
#[macro_export]
macro_rules! print_message {
() => {
println!("{}", crate::MESSAGE);

Use instead:
```
#[macro_export]
macro_rules! print_message {
() => {
println!("{}", $crate::MESSAGE);

macro definition, e.g.:

#[allow(clippy::crate_in_macro_def)]
macro_rules! ok { ... crate::foo ... }

Checks for function/method calls with a mutable

In release builds `debug_assert!` macros are optimized out by the
compiler.
Therefore mutating something in a `debug_assert!` macro results in different behavior
between a release and debug build.

@ -1,46 +0,0 @@
### What it does
Checks for declaration of `const` items which is interior
mutable (e.g., contains a `Cell`, `Mutex`, `AtomicXxxx`, etc.).
### Why is this bad?
Consts are copied everywhere they are referenced, i.e.,
every time you refer to the const a fresh instance of the `Cell` or `Mutex`
or `AtomicXxxx` will be created, which defeats the whole purpose of using
these types in the first place.
The `const` should better be replaced by a `static` item if a global
variable is wanted, or replaced by a `const fn` if a constructor is wanted.
### Known problems
A "non-constant" const item is a legacy way to supply an
initialized value to downstream `static` items (e.g., the
`std::sync::ONCE_INIT` constant). In this case the use of `const` is legit,
and this lint should be suppressed.
Even though the lint avoids triggering on a constant whose type has enums that have variants
with interior mutability, and its value uses non interior mutable variants (see
[#3962](https://github.com/rust-lang/rust-clippy/issues/3962) and
[#3825](https://github.com/rust-lang/rust-clippy/issues/3825) for examples);
it complains about associated constants without default values only based on its types;
which might not be preferable.
There're other enums plus associated constants cases that the lint cannot handle.
Types that have underlying or potential interior mutability trigger the lint whether
the interior mutable field is used or not. See issues
[#5812](https://github.com/rust-lang/rust-clippy/issues/5812) and
### Example
```
use std::sync::atomic::{AtomicUsize, Ordering::SeqCst};
const CONST_ATOM: AtomicUsize = AtomicUsize::new(12);
CONST_ATOM.store(6, SeqCst); // the content of the atomic is unchanged
assert_eq!(CONST_ATOM.load(SeqCst), 12); // because the CONST_ATOM in these lines are distinct
```
Use instead:
```
static STATIC_ATOM: AtomicUsize = AtomicUsize::new(15);
STATIC_ATOM.store(9, SeqCst);
assert_eq!(STATIC_ATOM.load(SeqCst), 9); // use a `static` item to refer to the same instance

src/docs/default_numeric_fallback.txt
View file

@ -1,28 +0,0 @@
### What it does
Checks for usage of unconstrained numeric literals which may cause default numeric fallback in type
inference.
Default numeric fallback means that if numeric types have not yet been bound to concrete
types at the end of type inference, then integer type is bound to `i32`, and similarly
floating type is bound to `f64`.
See [RFC0212](https://github.com/rust-lang/rfcs/blob/master/text/0212-restore-int-fallback.md) for more information about the fallback.
### Why is this bad?
For those who are very careful about types, default numeric fallback
can be a pitfall that cause unexpected runtime behavior.
### Known problems
This lint can only be allowed at the function level or above.

```
let i = 10;
let f = 1.23;

View file

@ -1,36 +0,0 @@
### What it does
Displays a warning when a union is declared with the default representation (without a `#[repr(C)]` attribute).
### Why is this bad?
Unions in Rust have unspecified layout by default, despite many people thinking that they
lay out each field at the start of the union (like C does). That is, there are no guarantees
about the offset of the fields for unions with multiple non-ZST fields without an explicitly
specified layout. These cases may lead to undefined behavior in unsafe blocks.
### Example
```
union Foo {
a: i32,
b: u32,
}
fn main() {
let _x: u32 = unsafe {
Foo { a: 0_i32 }.b // Undefined behavior: `b` is allowed to be padding
};
}

Use instead:
```
#[repr(C)]
union Foo {
a: i32,
b: u32,
}
fn main() {
let _x: u32 = unsafe {
Foo { a: 0_i32 }.b // Now defined behavior, this is just an i32 -> u32 transmute
};

processed before the PreExpansionPass lints get executed. See
