Implementations

impl NonterminalKind

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.

Trait Implementations

impl Clone for NonterminalKind

fn clone(&self) -> NonterminalKind

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

fn decode(__decoder: &mut __D) -> Result<Self, <__D as Decoder>::Error>

impl Display for NonterminalKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

fn encode(&self, __encoder: &mut __E) -> Result<(), <__E as Encoder>::Error>

impl PartialEq<NonterminalKind> for NonterminalKind

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

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