Don't call `walk_` functions directly if there is an equivalent `visit_` method I was working on https://github.com/rust-lang/rust/issues/77773 and realized in one of my experiments that the `visit_path` method was not always called whereas it should have. This fixes it. r? ``@davidtwco``
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:
