## Rust 1.91
Current stable, released 2025-10-30
[View all 146 merged pull requests](https://github.com/rust-lang/rust-clippy/pulls?q=merged%3A2025-07-25T21%3A05%3A11Z..2025-09-04T22%3A34%3A27Z+base%3Amaster)
### New Lints
* Added [`possible_missing_else`] to `suspicious`
[#15317](https://github.com/rust-lang/rust-clippy/pull/15317)
### Moves and Deprecations
* Moved [`cognitive_complexity`] from `nursery` to `restriction`
[#15415](https://github.com/rust-lang/rust-clippy/pull/15415)
* Moved [`declare_interior_mutable_const`] from `style` to `suspicious`
[#15454](https://github.com/rust-lang/rust-clippy/pull/15454)
* Moved [`crosspointer_transmute`] from `complexity` to `suspicious`
[#15403](https://github.com/rust-lang/rust-clippy/pull/15403)
### Enhancements
* [`excessive_precision`] added `const_literal_digits_threshold` option to suppress overly precise constants.
[#15193](https://github.com/rust-lang/rust-clippy/pull/15193)
* [`unwrap_in_result`] rewritten for better accuracy; now lints on `.unwrap()` and `.expect()`
directly and no longer mixes `Result` and `Option`.
[#15445](https://github.com/rust-lang/rust-clippy/pull/15445)
* [`panic`] now works in `const` contexts.
[#15565](https://github.com/rust-lang/rust-clippy/pull/15565)
* [`implicit_clone`] now also lints `to_string` calls (merging [`string_to_string`] behavior).
[#14177](https://github.com/rust-lang/rust-clippy/pull/14177)
* [`collapsible_match`] improved suggestions to handle necessary ref/dereferencing.
[#14221](https://github.com/rust-lang/rust-clippy/pull/14221)
* [`map_identity`] now suggests making variables mutable when required; recognizes tuple struct restructuring.
[#15261](https://github.com/rust-lang/rust-clippy/pull/15261)
* [`option_map_unit_fn`] preserves `unsafe` blocks in suggestions.
[#15570](https://github.com/rust-lang/rust-clippy/pull/15570)
* [`unnecessary_mut_passed`] provides structured, clearer fix suggestions.
[#15438](https://github.com/rust-lang/rust-clippy/pull/15438)
* [`float_equality_without_abs`] now checks `f16` and `f128` types.
[#15054](https://github.com/rust-lang/rust-clippy/pull/15054)
* [`doc_markdown`] expanded whitelist (`InfiniBand`, `RoCE`, `PowerPC`) and improved handling of
identifiers like NixOS.
[#15558](https://github.com/rust-lang/rust-clippy/pull/15558)
* [`clone_on_ref_ptr`] now suggests fully qualified paths to avoid resolution errors.
[#15561](https://github.com/rust-lang/rust-clippy/pull/15561)
* [`manual_assert`] simplifies boolean expressions in suggested fixes.
[#15368](https://github.com/rust-lang/rust-clippy/pull/15368)
* [`four_forward_slashes`] warns about bare CR in comments and avoids invalid autofixes.
[#15175](https://github.com/rust-lang/rust-clippy/pull/15175)
### False Positive Fixes
* [`alloc_instead_of_core`] fixed FP when `alloc` is an alias
[#15581](https://github.com/rust-lang/rust-clippy/pull/15581)
* [`needless_range_loop`] fixed FP and FN when meeting multidimensional array
[#15486](https://github.com/rust-lang/rust-clippy/pull/15486)
* [`semicolon_inside_block`] fixed FP when attribute over expr is not enabled
[#15476](https://github.com/rust-lang/rust-clippy/pull/15476)
* [`unnested_or_patterns`] fixed FP on structs with only shorthand field patterns
[#15343](https://github.com/rust-lang/rust-clippy/pull/15343)
* [`match_ref_pats`] fixed FP on match scrutinee of never type
[#15474](https://github.com/rust-lang/rust-clippy/pull/15474)
* [`infinite_loop`] fixed FP in async blocks that are not awaited
[#15157](https://github.com/rust-lang/rust-clippy/pull/15157)
* [`iter_on_single_items`] fixed FP on function pointers and let statements
[#15013](https://github.com/rust-lang/rust-clippy/pull/15013)
### ICE Fixes
* [`len_zero`] fix ICE when fn len has a return type without generic type params
[#15660](https://github.com/rust-lang/rust-clippy/pull/15660)
### Documentation Improvements
* [`cognitive_complexity`] corrected documentation to state lint is in `restriction`, not `nursery`
[#15563](https://github.com/rust-lang/rust-clippy/pull/15563)
### Performance Improvements
* [`doc_broken_link`] optimized by 99.77% (12M → 27k instructions)
[#15385](https://github.com/rust-lang/rust-clippy/pull/15385)
