Fix inconsistent cwd of `run` and `debug` command in client
Fix#17012. Also related to #13022 and #15993.
When the `kind` of runnable is `bin`, Cargo would use the workspace root as the cwd for the `run` command; otherwise, Cargo defaults to the package root as the cwd for `run`.
Initially, r-a assumed the workspace root as the cwd for all runnables in `debug` command, which led to issue #13022. In this case, during unit testing, the `run` command would use the package root while `debug` would use the workspace root, causing inconsistency.
PR #15993 addressed this problem by using the package root as the cwd for `debug` command. However, it also resulted in an inconsistency: when executing the `run` command within the main fn of a package (whose target is `bin`), Cargo would use the workspace root, whereas `debug` would use the package root, leading to issue #17012.
The preferable approach is to determine the cwd based on the runnable's type. To resolve this, this PR introduces a new `cwd` field within `CargoRunnable`, allowing r-a to decide the appropriate cwd depending on the specific kind of the runnable.
Allow sysroots to only consist of the source root dir
Fixes https://github.com/rust-lang/rust-analyzer/issues/17159
This PR encodes the `None` case of an optional sysroot into `Sysroot` itself. This simplifies a lot of things and allows us to have sysroots that consist of nothing, only standard library sources, everything but the standard library sources or everything. This makes things a lot more flexible. Additionally, this removes the workspace status bar info again, as it turns out that that can be too much information for the status bar to handle (this is better rendered somewhere else, like in the status view).
Fix: infer type of async block with tail return expr
Fixes#17106
The `infer_async_block` method calls the `infer_block` method internally, which returns the never type without coercion when `tail_expr` is `None` and `ctx.diverges` is `Diverges::Always`.This is the reason for the bug in this issue.
cfce2bb46d/crates/hir-ty/src/infer/expr.rs (L1411-L1413)
This PR solves the bug by adding a process to coerce after calling `infer_block` method.
This code passes all the tests, including tests I added for this isuue, however, I am not sure if this solution is right. I think that this solution is an ad hoc solution. So, I would appreciate to have your review.
I apologize if I'm off the mark, but `infer_async_block` method should be rewritten to share code with the process of infering type of `expr::Closure` instead of the `infer_block` method. That way it will be closer to the infer process of rustc.
handle {self} when removing unused imports
Fixes#17139
On master
```rs
mod inner {
pub struct X();
pub struct Y();
}
mod z {
use super::inner::{self, X}$0;
fn f() {
let y = inner::Y();
}
}
```
becomes
```rs
mod inner {
pub struct X();
pub struct Y();
}
mod z {
use super::inner:self;
fn f() {
let y = inner::Y();
}
}
```
with this fix it instead becomes
```
```rs
mod inner {
pub struct X();
pub struct Y();
}
mod z {
use super::inner;
fn f() {
let y = inner::Y();
}
}
```
fix: ensure implied bounds from associated types are considered in autocomplete
closes: #16989
rust-analyzer needs to consider implied bounds from associated types in order to get all methods suggestions people expect. A pretty easy way to do that is to keep the `candidate_trait_id`'s receiver if it matches `TyFingerprint::Unnameable`. When benchmarking this change, I didn't notice a meaningful difference in autocomplete latency.
(`TyFingerprint::Unnameable` corresponds to `TyKind::AssociatedType`, `TyKind::OpaqueType`, `TyKind::FnDef`, `TyKind::Closure`, `TyKind::Coroutine`, and `TyKind::CoroutineWitness`.)
internal: refactor `prefer_no_std`/`prefer_prelude` bools into a struct
I noticed that there's a large number of functions/arguments during an unrelated change that take two booleans and realized they're _probably_ better off being in a single struct—less error-prone, etc.
Feel free to suggest a better name than `ImportPathConfig`/close this entirely! I can also make these args enums; just hopefully making this a little more misuse-resistant.
Clear diagnostics only after new ones were received
Closes#15934
This adds a flag inside the global state which controls when old diagnostics are cleared. Now, old diagnostics should be cleared only after at least one new diagnostic is available.
feat: More callable info
With this PR we retain more info about callables other than functions, allowing for closure parameter type inlay hints to be linkable as well as better signature help around closures and `Fn*` implementors.
alloc: implement FromIterator for Box<str>
`Box<[T]>` implements `FromIterator<T>` using `Vec<T>` + `into_boxed_slice()`.
Add analogous `FromIterator` implementations for `Box<str>`
matching the current implementations for `String`.
Remove the `Global` allocator requirement for `FromIterator<Box<str>>` too.
