Struct Token 

pub struct Token {
    pub kind: TokenKind,
    pub line: usize,
    pub col: usize,
    pub lo: u32,
    pub hi: u32,
}

Fields

kind: TokenKind

line: usize

col: usize

lo: u32

Byte offset of the token’s first byte into the source.

hi: u32

Byte offset one past the token’s last byte.

Implementations

impl Token

pub fn new(kind: TokenKind, line: usize, col: usize) -> Self

Construct with lo/hi left as 0; Tokenizer::next_token stamps the real byte offsets after the token is read (a single point, so the per-kind helpers don’t each need to track offsets).

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a duplicate of the value.

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 ==.

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

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