Fields

inferred: bool

Keep track of whether the user used :pat_param or :pat and we inferred it from the edition of the span. This is used for diagnostics.

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

Trait Implementations

source

impl Clone for NonterminalKind

source

fn clone(&self) -> NonterminalKind

Returns a copy of the value. Read more

1.0.0 · source

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

Performs copy-assignment from source. Read more

source

impl Debug for NonterminalKind

source

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

Formats the value using the given formatter. Read more

source

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

Formats the value using the given formatter. Read more

source

impl<E: Encoder> Encodable<E> for NonterminalKind

source

fn encode(&self, encoder: &mut E)

source

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 ==. Read more

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. Read more

source

impl<T, U> Into for Twhere
U: From<T>,

const: unstable · source

fn into(self) -> U

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.

source

impl<T, U> TryFrom for Twhere
U: Into<T>,

type Error = Infallible

The type returned in the event of a conversion error.

const: unstable · source

fn try_from(value: U) -> Result<T, <T as TryFrom>::Error>

Performs the conversion.

source

impl<T, U> TryInto for Twhere
U: TryFrom<T>,

type Error = >::Error

The type returned in the event of a conversion error.

const: unstable · source

fn try_into(self) -> Result<U, >::Error>

Performs the conversion.

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.
