Add inefficient_to_string lint 2019-10-16 15:54:20 -04:00

cc622608db new lints around #[must_use] fns 
`must_use_unit` lints unit-returning functions with a `#[must_use]`
attribute, suggesting to remove it.

`double_must_use` lints functions with a plain `#[must_use]`
attribute, but which return a type which is already `#[must_use]`,
so the attribute has no benefit.

`must_use_candidate` is a pedantic lint that lints functions and
methods that return some non-unit type that is not already
`#[must_use]` and suggests to add the annotation.

b690cdb1e7 Auto merge of #4611 - rust-lang:doc-visibility, r=flip1995 
account for doc visibility

This fixes #4608.

Also I noticed that the lint failed to look at trait and impl items. There's a small bit of fallout in the code, too, but not enough to warrant its own commit.

changelog: check docs of trait items and impl items, also make `missing_safety_doc` account for visibility

Add manual_saturating_arithmetic lint

changelog: add `manual_saturating_arithmetic` lint

Fixes #1557. This lint detects manual saturating arithmetics like `x.checked_add(10u32).unwrap_or(u32::max_value())` and suggests replacing with `x.saturating_add(10u32)`.

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 😺

73458aebe3 Merge #3368 
3368: added downsides to "known problems" for get_unwrap lint r=flip1995 a=humean

As a beginner I found this lint to be confusing because I was not sure how the `Option` type disappeared as conceptually I know that my `.get()` and Index could fail. Initially I thought maybe the compiler or clippy was smart enough to understand that it was impossible for my `.get()` to fail in this particular case, but it was explained to me that using the Index syntax is just shorthand for directly unwrapping the value:

https://doc.rust-lang.org/src/std/collections/hash/map.rs.html#1547

For beginners or users trying to iterate quickly it seems common to litter your code with `unwrap` or `except` as placeholders for where some explicit error handling might need to take place. I think it should be warned that using Index is merely more concise, but doesn't at all reduce the risk of panics and might in fact cause you to miss handling them in a future refactor.

d3c06f7252 Exclude pattern guards from unnecessary_fold lint 
Methods like `Iterator::any` borrow the iterator mutably,
which is not allowed within a pattern guard and will fail to compile.
This commit prevents clippy from suggesting this type of change.
