update to literal-escaper-0.0.5 Quoting from the changelog, this version brings: - Use `NonZero<char/u8>` in `unescape_c_str` and `check_raw_c_str` to statically exclude nuls - Add `#[inline]` to small functions for improved performance
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:
