Struct Token

pub struct Token {
    pub ty: TokenKind,
    pub data: TokenData,
    pub line: u32,
    pub col: u32,
}

Contains a single unit of lexical information, and an optional bit of TokenData

Fields

ty: TokenKind

data: TokenData

line: u32

col: u32

Implementations

impl Token

pub fn new( ty: TokenKind, data: impl Into<TokenData>, line: u32, col: u32, ) -> Self

Creates a new Token out of a TokenKind, TokenData, line, and column.

pub fn cast(self, ty: TokenKind) -> Self

Casts this token to a new TokenKind

pub fn ty(&self) -> TokenKind

Returns the TokenKind of this token

pub fn data(&self) -> &TokenData

Returns a reference to this token’s TokenData

pub fn into_data(self) -> TokenData

Converts this token into its inner TokenData

pub fn line(&self) -> u32

Returns the line where this token originated

pub fn col(&self) -> u32

Returns the column where this token originated

Trait Implementations

impl Clone for Token

fn clone(&self) -> Token

Returns a copy 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.
