Limit the ``[`identity_op`]`` lint to integral operands.
changelog: limit ``[`identity_op`]`` to integral operands
In the ``[`identity_op`]`` lint, if the operands are non-integers, then the lint is likely
wrong.
Fixed issues with to_radians and to_degrees lints
fixes#7651
I fixed the original problem as described in the issue, but the bug remains for complex expressions (the commented out TC I added is an example). I would also love some feedback on how to cleanup my code and reduce duplication. I hope it's not a problem that the issue has been claimed by someone else - that was over two months ago.
changelog: ``[`suboptimal_flops`]`` no longer proposes broken code with `to_radians` and `to_degrees`
Fix `enum_variants` FP on prefixes that are not camel-case
closes#8090
Fix FP on `enum_variants` when prefixes are only a substring of a camel-case word. Also adds some util helpers on `str_utils` to help parsing camel-case strings.
This changes how the lint behaves:
1. previously if the Prefix is only a length of 1, it's going to get ignored, i.e. these were previously ignored and now is warned
```rust
enum Foo {
cFoo,
cBar,
cBaz,
}
enum Something {
CCall,
CCreate,
CCryogenize,
}
```
2. non-ascii characters that doesn't have casing will not be split,
```rust
enum NonCaps {
PrefixXXX,
PrefixTea,
PrefixCake,
}
```
will be considered as `PrefixXXX`, `Prefix`, `Prefix`, so this won't lint as opposed to fired previously.
changelog: [`enum_variant_names`] Fix FP when first prefix are only a substring of a camel-case word.

`needless_return` suggest return unit type on void returns
closes#8177
previously, `needless_return` suggests an empty block `{}` to replace void `return` on match arms, this PR improve the suggestion by suggesting a unit instead.

cache test item names
This avoids quadratic behavior (collecting all test item names for each `eq_op` instance within the module). However, it invests a good deal of memory to buy this speedup. If that becomes a problem, I may need to change the cache to only store the chain of last visited modules.
This hopefully fixes#8171.

`enum_variant_names` will consider characters with no case to be a part
of prefixes/suffixes substring that are compared. This means `Foo1` and
`Foo2` has different prefixes (`Foo1` and `Foo2` prefix respeectively).
This applies to all non-ascii characters with no casing.
fix an ICE on unwrapping a None
This very likely fixes#8166 though I wasn't able to meaningfully reduce a test case. This line is the only call to `unwrap` within that function, which was the one in the stack trace that triggered the ICE, so I think we'll be OK.
`@hackmad` can you pull and build this branch and check if it indeed fixes your problem?

Improve `unwrap_or_else_default` when handling `unwrap_or_else(XXX::new)`
changelog: change `unwrap_or_else_default` to work with std constructors like `Vec::new`, `HashSet::new`, `HashMap::new`.
Notes:
- Code to handle detecting those constructors is already there. I moved it out to `is_default_equivalent_call`
