Struct Token 

pub struct Token<'a> {
    pub kind: TokenKind,
    pub text: &'a str,
    pub start: usize,
}

One lexical token: kind, the source slice it covers, and the byte offset it starts at.

The text is borrowed from the expression — lexing allocates nothing but the returned Vec.

Fields

kind: TokenKind

What the token is.

text: &'a str

The exact source text, delimiters and escapes included.

start: usize

Byte offset of the token in the expression.

Implementations

impl Token<'_>

pub fn end(&self) -> usize

The byte offset one past the token’s last byte.
