Provided Associated Constants§
sourceconst VISIT_TOKENS: bool = false
const VISIT_TOKENS: bool = false
Mutable token visiting only exists for the macro_rules
token marker and should not be
used otherwise. Token visitor would be entirely separate from the regular visitor if
the marker didn’t have to visit AST fragments in nonterminal tokens.

Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
