Struct Token 

pub struct Token {
    pub kind: TokenKind,
    pub span: Span,
}

A token with its span in the source code.

Fields

kind: TokenKind

The kind of token.

span: Span

The location in the source code.

Implementations

impl Token

pub const fn new(kind: TokenKind, span: Span) -> Self

Creates a new token.

pub const fn is_eof(&self) -> bool

Returns true if this is an EOF token.

pub const fn is_keyword(&self) -> bool

Returns true if this is a keyword.

pub const fn as_keyword(&self) -> Option<Keyword>

Returns the keyword if this is a keyword token.

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.
