changelog: bugfix for long strings as bytes
make needless_return work with void functions
fixes https://github.com/rust-lang/rust-clippy/issues/4181.
changelog: make needless_return work with void functions.
I don't think the failure is related to my changes, but I'm not sure 🤔
Downgrade integer_division to restriction
I believe that this lint falls outside of the scope of opinionated pedantism of the other pedantic lints.
changelog: Downgrade integer_division lint from pedantic to restriction
lint does not trigger when there is a difference in mutability
lint does not trigger when the method belongs to a trait which is not implemebted directly (Deref)
Fixing eta with respect to lazy evaluation.
This fixes#4187
changelog: `redundant_closure`: stop linting on expressions returning a function, which is then directly used by the closure
Add example to needless_range_loop
adds a "could be written as" example
btw, is it correct that the lint triggers even if the index is used not just for getting the values by index?
So that I have to add `.iter().enumerate()` to still get an index?
changelog: none
trivially_copy_pass_by_ref: print size of type and limit in the lint message
changelog: trivially_copy_pass_by_ref: print size of type and limit in the lint message
Fix match_same_arms to fail late
Changes:
- Add a function search_same_list which return a list of matched expressions
- Change the match_same_arms implementation behavior. It will lint each same arms found.
fixes#4096
changelog: none
Implement "Use last" lint
Closes#3673
This lint checks the use of `x.get(x.len() - 1)` and suggests `x.last()` (where `x` is a `Vec`).
There's at least one more thing that needs to happen here. I believe I am correctly checking most of the scenarios and avoiding false positives. However, if different `Vec`s are used for the `x.get` and `y.len`, then it will emit a false positive. In other words, I need to check to make sure the `Vec`s are the same.
Also, a lot of these commits were temporary and not helpful to the project history...am I supposed to squash on merge? If so, how do I do that?
changelog: New lint: `get_last_with_len`
Added lint for TryFrom for checked integer conversion.
works towards #3947
Added lint for try_from for checked integer conversion.
Should recognize simple & straight-forward checked integer conversions.
Changes:
- Add a function search_same_list which return a list of matched expressions
- Change the match_same_arms implementation behaviour. It will lint each same arms found.
Move the method checking into a new lint called
`redundant_closures_for_method_calls` and put it in the pedantic group.
This aspect of the lint seems more controversial than the rest.
cc #3942
Fix#4033 search_is_some
Fixes#4033.
Suggest `any(|x| ..)` instead of `any(|&x| ..)` for `find(|&x| ..).is_some()` (Lint [search_is_some](https://rust-lang.github.io/rust-clippy/master/index.html#search_is_some))
FnDecl of `find`:
```rust
fn find<P>(&mut self, mut p: P) -> Option<Self::Item> where
P: FnMut(&Self::Item) -> bool
```
FnDecl of `any`:
```rust
fn any<F>(&mut self, mut f: F) -> bool where
F: FnMut(Self::Item) -> bool
```
If match on `|&_|` in closure of `find`, only use `|_|` in the suggestion.
PS. It's the first time that I have used the `hir` API, please correct me if there is any mistake 😺
useless_let_if_seq handle interior mutability
fixes#3043
This passes all tests, including a new one specifically dealing with a type with interior mutability. The main thing I'm unsure of is whether the span I used in the call to `is_freeze` is the most appropriate span to use, or if it matters.
Suggest .copied() for map_clone on iterators too
fixes https://github.com/rust-lang/rust-clippy/issues/3958
changelog: Make `map_clone` suggest the newly-stable `Iterator::copied()` when applicable
r? @mikerite @matthiaskrgr
Do not trigger redundant_closure for non-function types
fixes#3898
Added a check for the entity being called in the closure body to be a FnDef. This way lint does not trigger for ADTs (Box) but I'm not sure if it's correct and not too restrictive.
