All token and node kinds. Tokens first, then nodes, then __LAST sentinel. #[repr(u16)] enables safe transmute in kind_from_raw.

DoubleColon

:: for type annotations. Defined before Colon for correct precedence.

Implementations

impl SyntaxKind

pub fn is_trivia(self) -> bool

pub fn is_error(self) -> bool

Trait Implementations

impl Clone for SyntaxKind

fn clone(&self) -> SyntaxKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SyntaxKind

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

Formats the value using the given formatter.

impl From<SyntaxKind> for SyntaxKind

fn from(kind: SyntaxKind) -> Self

Converts to this type from the input type.

impl Hash for SyntaxKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'s> Logos<'s> for SyntaxKind

type Error = ()

Error type returned by the lexer. This can be set using #[logos(error = MyError)]. Defaults to () if not set.

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>, ) -> Option<Result<Self, <Self as Logos<'s>>::Error>>

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 SyntaxKind

fn cmp(&self, other: &SyntaxKind) -> 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 SyntaxKind

fn eq(&self, other: &SyntaxKind) -> 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 SyntaxKind

fn partial_cmp(&self, other: &SyntaxKind) -> 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.
