Removing RHS snippet from SHADOW_UNRELATED message.
Fixes#5703
I am not sure if I reinvented the wheel here, but I could not really find a snippet function that did this truncation, so I created the function. Please tell me if there was a more obvious way to do this, I am new here. 😄
changelog: Truncates multi-line RHS in shadow_unrelated message if it has more than 5 lines.
improve advice in iter_nth_zero
fixes#5783
*Please keep the line below*
changelog: For iter_nth_zero, the "use .next()" replacement advice is on the last line of the code snippet, where it is vulnerable to truncation. Display that advice at the beginning instead.
Reprise: new lint: Unintentional return of unit from closures expecting Ord
This lint catches cases where the last statement of a closure expecting
an instance of Ord has a trailing semi-colon. It compiles since the
closure ends up return () which also implements Ord but causes
unexpected results in cases such as sort_by_key.
Fixes#5080
Reprise of #5348 where I addressed all the comments there
changelog: add lint [`unit_return_expecting_ord`]
This lint catches cases where the last statement of a closure expecting
an instance of Ord has a trailing semi-colon. It compiles since the
closure ends up return () which also implements Ord but causes
unexpected results in cases such as sort_by_key.
Fixes#5080
reprise: rebase, update and address all concerns
Rename collapsable_if fix suggestion to "collapse nested if block"
The name "try" is confusing when shown as quick fix by rust-analyzer
changelog: Rename `collapsable_if` fix suggestion to "collapse nested if block"
The "use .next()" replacement advice is on the last line of the code snippet,
where it is vulnerable to truncation. Display that advice at the beginning
instead.
closes#5783
Fix out of bounds access by checking length equality BEFORE accessing by index.
Fixes#5780
changelog: fix out of bounds access in unnested_or_patterns lint.
Edit: I did not bother reducing a testcase from `librustc_typeck` crate but I can confirm that with the change the crash no longer occurs.
Move range_minus_one to pedantic
This moves the range_minus_one lint to the pedantic category, so there
will not be any warnings emitted by default. This should work around
problems where the suggestion is impossible to resolve due to the range
consumer only accepting a specific range implementation, rather than the
`RangeBounds` trait (see #3307).
While it is possible to work around this by extracting the boundary into
a variable, I don't think clippy should encourage people to disable or
work around lints, but instead the lints should be fixable. So hopefully
this will help until a proper implementation checks what the range is
used for.

Some accuracy lints for floating point operations
This will add some lints for accuracy on floating point operations suggested by @clarfon in #2040 (fixes#2040).
These are the remaining lints:
- [x] x.powi(2) => x * x
- [x] x.logN() / y.logN() => x.logbase(y)
- [x] x.logbase(E) => x.log()
- [x] x.logbase(10) => x.log10()
- [x] x.logbase(2) => x.log2().
- [x] x * PI / 180 => x.to_radians()
- [x] x * 180 / PI => x.to_degrees()
- [x] (x + 1).log() => x.log_1p()
- [x] sqrt(x * x + y * y) => x.hypot(y)
changelog: Included some accuracy lints for floating point operations
Stabilize `transmute` in constants and statics but not const fn

new lint: match_like_matches_macro
Suggests using the `matches!` macro from `std` where appropriate.
`redundant_pattern_matching` has been moved into the `matches` pass to allow suppressing the suggestion where `is_some` and friends are a better replacement.

typeck: adding type information to projection
This commit modifies the Place as follow:
* remove 'ty' from ProjectionKind
* add type information into to Projection
* replace 'ty' in Place with 'base_ty'
* introduce 'ty()' in `Place` to return the final type of the `Place`
* introduce `ty_before_projection()` in `Place` to return the type of
a `Place` before i'th projection is applied
