Fields of PatParam

inferred: bool

Keep track of whether the user used :pat_param or :pat and we inferred it from the edition of the span. This is used for diagnostics.

Implementations

impl NonterminalKind[src]

pub fn from_symbol(
    symbol: Symbol,
    edition: impl FnOnce() -> Edition
) -> Option<NonterminalKind>[src]

The edition closure is used to get the edition for the given symbol. Doing span.edition() is expensive, so we do it lazily.
