Struct Token

pub struct Token {
    pub kind: TokenKind,
    pub start: usize,
    pub len: usize,
}

The struct to represent a token.

Token contains the kind of token and the range of the token in the source. The range is represented by the start position and the length of the token.

Note!: This struct can live longer than the source string.

Fields

kind: TokenKind

The kind of the token.

start: usize

The start position of the token.

len: usize

The length of the token.

Implementations

impl Token

pub fn range(&self) -> Range<usize>

Get the range of the token.

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Token

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

Formats the value using the given formatter.

impl PartialEq for Token

fn eq(&self, other: &Token) -> 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 Copy for Token

impl Eq for Token
