|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 93: Support leading pipe in match arms r=matklad a=DJMcNab This adds support for match arms of the form: ```rust <...> | X | Y => <...>, | X => <...>, | 1..2 => <...>, etc ``` # Implementation discussion This just naïvely 'eats' a leading pipe if one is available. The equivalent line in the reference `libsyntax` is in [`parse_arm`](https://github.com/rust-lang/rust/blob/441519536c8bd138e8c651743249acd6814747a1/src/libsyntax/parse/parser.rs#L3552). As noted in the comment linked above, this feature was formally introduced as a result of rust-lang/rfcs#1925. This feature is in active use in the [`rust-analyzer` codebase](https://github.com/matklad/rust-analyzer/blob/c87fcb4ea5874a7307c1d9d1192e923f3ae2c922/crates/ra_syntax/src/syntax_kinds/generated.rs#L231) I have added some tests for this feature, but maybe more would be required EDIT: Always looking for feedback - is this PR description over-engineered?
