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<NonterminalKind> 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.

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.
