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:
