Trait Implementations

impl Clone for Sym

fn clone(&self) -> Sym

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sym

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

Formats the value using the given formatter.

impl<'s> Logos<'s> for Sym

const ERROR: Self = Sym::Error

Helper const of the variant marked as #[error].

type Extras = ()

Associated type Extras for the particular lexer. This can be set using #[logos(extras = MyExtras)] and accessed inside callbacks.

type Source = str

Source type this token can be lexed from. This will default to str, unless one of the defined patterns explicitly uses non-unicode byte values or byte slices, in which case that implementation will use [u8].

fn lex(lex: &mut Lexer<'s, Self>)

The heart of Logos. Called by the Lexer. The implementation for this function is generated by the logos-derive crate.

fn lexer(source: &'source Self::Source) -> Lexer<'source, Self>

where Self::Extras: Default,

Create a new instance of a Lexer that will produce tokens implementing this Logos.

fn lexer_with_extras( source: &'source Self::Source, extras: Self::Extras, ) -> Lexer<'source, Self>

Create a new instance of a Lexer with the provided Extras that will produce tokens implementing this Logos.

impl Ord for Sym

fn cmp(&self, other: &Sym) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Sym

fn eq(&self, other: &Sym) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for Sym

fn partial_cmp(&self, other: &Sym) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
