move some strings into consts, more tests
s/missing_field_in_debug/missing_fields_in_debug
dont trigger in macro expansions
make dogfood tests happy
minor cleanups
replace HashSet with FxHashSet
replace match_def_path with match_type
if_chain -> let chains, fix markdown, allow newtype pattern
fmt
consider string literal in `.field()` calls as used
don't intern defined symbol, remove mentions of 'debug_tuple'
special-case PD, account for field access through `Deref`
Add new lint `ptr_cast_constness`
This adds a new lint which functions as the opposite side of the coin to `ptr_as_ptr`. Rather than linting only as casts that don't change constness, this lints only constness; suggesting to use `pointer::cast_const` or `pointer::cast_mut` instead.
changelog: new lint [`ptr_cast_constness`]
fix: warn on empty line outer AttrKind::DocComment
changelog: [`empty_line_after_doc_comments`]: add lint for checking empty lines after rustdoc comments.
Fixes: #10395
Fixes#10609: Adds lint to detect construction of unit struct using `default`
Using `default` to construct a unit struct increases code complexity and adds a function call. This can be avoided by simply removing the call to `default` and simply construct by name.

New lint: detect `if` expressions with simple boolean assignments to the same target
Closes#10430
changelog: [`needless_bool_assign`] new lint to detect simple boolean assignment to the same target in `if` branches
Added the `[unnecessary_box_returns]` lint
fixes#5
I'm not confident in the name of this lint. Let me know if you can think of something better

Add `collection_is_never_read`
Fixes#9267
`@flip1995` and `@llogiq,` I talked with you about this one at Rust Nation in London last week. :-)
This is my first contribution to Clippy, so lots of feedback would be greatly appreciated.
- \[ ] Followed [lint naming conventions][lint_naming]
- \[x] Added passing UI tests (including committed `.stderr` file)
- \[x] `cargo test` passes locally
- \[x] Executed `cargo dev update_lints`
- \[x] Added lint documentation
- \[x] Run `cargo dev fmt`
`dogfood` found one true positive (see #9509) and no false positives.
`lintcheck` found no (true or false) positives, even when running on an extended set of crates.
