Implementations

impl Nonterminal[src]

fn span(&self) -> Span[src]

pub fn pretty_printing_compatibility_hack(&self) -> bool[src]

This nonterminal looks like some specific enums from proc-macro-hack and procedural-masquerade crates. We need to maintain some special pretty-printing behavior for them due to incorrect asserts in old versions of those crates and their wide use in the ecosystem. See issue #73345 for more details. FIXME(#73933): Remove this eventually.
