2022-04-30Add `do yeet` expressions to allow experimentation in nightlyScott McMurray-1/+3
Using an obviously-placeholder syntax. An RFC would still be needed before this could have any chance at stabilization, and it might be removed at any point. But I'd really like to have it in nightly at least to ensure it works well with try_trait_v2, especially as we refactor the traits.

The change looks big because `rustfmt` rearranges things, but the only real change is the inlining annotation.

Fix bug with `#[doc]` string single-character last lines Fixes #90618. This is because `.iter().all(|c| c == '*')` returns `true` if there is no character checked. And in case the last line has only one character, it simply returns `true`, making the last line behind removed.

2020-11-24Move lev_distance to rustc_ast, make non-genericArlie Davis-168/+0
rustc_ast currently has a few dependencies on rustc_lexer. Ideally, an AST would not have any dependency its lexer, for minimizing unnecessarily design-time dependencies. Breaking this dependency would also have practical benefits, since modifying rustc_lexer would not trigger a rebuild of rustc_ast. This commit does not remove the rustc_ast --> rustc_lexer dependency, but it does remove one of the sources of this dependency, which is the code that handles fuzzy matching between symbol names for making suggestions in diagnostics. Since that code depends only on Symbol, it is easy to move it to rustc_span. It might even be best to move it to a separate crate, since other tools such as Cargo use the same algorithm, and have simply contain a duplicate of the code. This changes the signature of find_best_match_for_name so that it is no longer generic over its input. I checked the optimized binaries, and this function was duplicated at nearly every call site, because most call sites used short-lived iterator chains, generic over Map and such. But there's no good reason for a function like this to be generic, since all it does is immediately convert the generic input (the Iterator impl) to a concrete Vec<Symbol>. This has all of the costs of generics (duplicated method bodies) with no benefit. Changing find_best_match_for_name to be non-generic removed about 10KB of code from the optimized binary. I know it's a drop in the bucket, but we have to start reducing binary size, and beginning to tame over-use of generics is part of that.
