Implementations

impl Nonterminal

pub fn span(&self) -> Span

Trait Implementations

impl Clone for Nonterminal

fn clone(&self) -> Nonterminal

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Nonterminal

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

Formats the value using the given formatter.

impl<__D: Decoder> Decodable<__D> for Nonterminal

fn decode(__decoder: &mut __D) -> Self

impl<__E: Encoder> Encodable<__E> for Nonterminal

fn encode(&self, __encoder: &mut __E)

impl HasTokens for Nonterminal

fn tokens(&self) -> Option<&LazyAttrTokenStream>

fn tokens_mut(&mut self) -> Option<&mut Option<LazyAttrTokenStream>>

impl<CTX> HashStable<CTX> for Nonterminalwhere
    CTX: HashStableContext,

fn hash_stable(&self, _hcx: &mut CTX, _hasher: &mut StableHasher)

impl PartialEq<Nonterminal> for Nonterminal

fn eq(&self, rhs: &Self) -> bool

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

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.
