Implement pin-project in pattern matching for `&pin mut|const T` This PR implements part of rust-lang/rust#130494. It supports pin-project in pattern matching for `&pin mut|const T`. ~Pin-projection by field access (i.e. `&pin mut|const place.field`) is not fully supported yet since pinned-borrow is not ready (rust-lang/rust#135731).~ CC ``````@traviscross``````
The rustc_ast crate contains those things concerned purely with syntax
– that is, the AST ("abstract syntax tree"), along with some definitions for tokens and token streams, data structures/traits for mutating ASTs, and shared definitions for other AST-related parts of the compiler (like the lexer and macro-expansion).
For more information about how these things work in rustc, see the rustc dev guide:
