Implementations

impl Nonterminal

pub fn span(&self) -> Span

Trait Implementations

impl AstLike for Nonterminal

const SUPPORTS_CUSTOM_INNER_ATTRS: bool

This is true if this AstLike might support ‘custom’ (proc-macro) inner attributes. Attributes like #![cfg] and #![cfg_attr] are not considered ‘custom’ attributes

fn attrs(&self) -> &[Attribute]

fn visit_attrs(&mut self, f: impl FnOnce(&mut Vec<Attribute>))

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

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) -> Result<Self, <__D as Decoder>::Error>

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

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

impl<CTX> HashStable<CTX> for Nonterminal where
    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 ==.

#[must_use]

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

This method tests for !=.
