Enum wagon_lexer::Tokens

pub enum Tokens {
    ProductionToken(Productions),
    MathToken(Math),
    MetadataToken(Metadata),
}

An enum that holds the different types of tokens for the different lexers.

Variants

ProductionToken(Productions)

Tokens created by the Productions lexer.

MathToken(Math)

Tokens created by the Math lexer.

MetadataToken(Metadata)

Tokens created by the Metadata lexer.

Trait Implementations

impl Clone for Tokens

fn clone(&self) -> Tokens

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Tokens

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

Formats the value using the given formatter.

impl Default for Tokens

fn default() -> Self

Returns the “default value” for a type.

impl Display for Tokens

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

Formats the value using the given formatter.

impl PartialEq for Tokens

fn eq(&self, other: &Tokens) -> 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.

impl<'source> ResultNext<Tokens, LexingError> for LexerBridge<'source>

fn next_result(&mut self) -> Result<Tokens, LexingError>

If you have an iterator that holds Result items, you start having to deal with nested Some(Ok(...)) patterns, which gets annoying quickly. This trait is intended so that the iterator always returns some sort of Result, which can then be unwrapped as needed (probably using ?).

impl<'source> ResultPeek<Tokens, LexingError> for LexerBridge<'source>

fn peek_result(&mut self) -> Result<&Tokens, LexingError>

See next_result.

impl StructuralPartialEq for Tokens
