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 ==.

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

This method tests for !=.

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.
