![]() Clean up AstConv Split off from #120926 to make it only contain the renaming & (doc) comment updates. Any changes other than that which have accumulated over time are now part of this PR. Let's be disciplined ;) Inspired by https://github.com/rust-lang/rust/pull/120926#issuecomment-1997984483. --- * Remove `hir_trait_to_predicates` * Unused since #113671 * Inline `create_args_for_ast_trait_ref` * Only had a single call site * Having it as a separate method didn't gain us anything * Use an if-let guard somewhere to avoid unwrapping * Avoid explicit trait object lifetimes * More legible, stylistic-only (the updated code is 100% semantically identical) * Use explicitly elided lifetimes in impl headers, they get elaborated to distinct lifetimes * Make use of [object lifetime defaulting](https://doc.rust-lang.org/reference/lifetime-elision.html#default-trait-object-lifetimes) for a trait object type inside of a reference type somewhere * Use preexisting dedicated method `ItemCtxt::to_ty` over `<dyn AstConv<'_>>::ast_ty_to_ty` * Use preexisting dedicated method `AstConv::astconv` over explicit coercions * Simplify the function signature of `create_args_for_ast_path` and of `check_generic_arg_count` * In both cases redundant information was passed rendering the call sites verbose and confusing * No perf impact (tested in [#120926](https://github.com/rust-lang/rust/pull/120926)) * Move diagnostic method `report_ambiguous_associated_type` from `astconv` to `astconv::errors` * The submodule `errors` exists specifically for that purpose * Use it to keep the main module clean & short |
