Struct Token

pub struct Token<L: Lexicon> {
    pub span: Span,
    pub ty: L,
}

Item produced by a lexer, which holds the token type and the source span

Fields

span: Span

Position of this token in the source

ty: L

Type of this token

Implementations

impl<L: Lexicon> Token<L>

pub fn new<TSpan: Into<Span>>(span: TSpan, ty: L) -> Self

Create a new Token

pub fn src<'s>(&self, input: &'s str) -> &'s str

Get the source of this token from the entire source input

pub fn to_src<'s>(&self, input: &'s str) -> TokenSrc<'s, L>

Get the content of this token as a TokenSrc from the entire source input

Trait Implementations

impl<L: Clone + Lexicon> Clone for Token<L>

fn clone(&self) -> Token<L>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<L: Lexicon> Debug for Token<L>

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

Formats the value using the given formatter.

impl<L: Lexicon> From<Cell<L>> for Token<L>

fn from(cell: Cell<L>) -> Self

Converts to this type from the input type.

impl<L: Lexicon> From<Token<L>> for Cell<L>

fn from(token: Token<L>) -> Self

Converts to this type from the input type.

impl<L: Hash + Lexicon> Hash for Token<L>

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<L: PartialEq + Lexicon> PartialEq for Token<L>

fn eq(&self, other: &Token<L>) -> bool

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

const 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<L: Lexicon> ToSpan for Token<L>

fn lo(&self) -> Pos

fn hi(&self) -> Pos

fn span(&self) -> Span

impl<L: Copy + Lexicon> Copy for Token<L>

impl<L: Eq + Lexicon> Eq for Token<L>
