Implementations§

source§

impl NonterminalKind

source

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

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

source

fn symbol(self) -> Symbol

impl PartialEq for NonterminalKind

source§

fn eq(&self, other: &NonterminalKind) -> bool

This method tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
