Trait Implementations

impl MutVisitor for Marker

fn token_visiting_enabled(&self) -> bool

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.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
