[`useless_conversion`]: only lint on paths to fn items and fix FP in macro Fixes #11065 (which is actually two issues: an ICE and a false positive) It now makes sure that the function call path points to a function-like item (and not e.g. a `const` like in the linked issue), so that calling `TyCtxt::fn_sig` later in the lint does not ICE (fixes https://github.com/rust-lang/rust-clippy/issues/11065#issuecomment-1616836099). It *also* makes sure that the expression is not part of a macro call (fixes https://github.com/rust-lang/rust-clippy/issues/11065#issuecomment-1616919639). ~~I'm not sure if there's a better way to check this other than to walk the parent expr chain and see if any of them are expansions.~~ (edit: it doesn't do this anymore) changelog: [`useless_conversion`]: fix ICE when call receiver is a non-fn item changelog: [`useless_conversion`]: don't lint if argument is a macro argument (fixes a FP) r? `@llogiq` (reviewed #10814, which introduced these issues) |
