Struct Token 

pub struct Token<'a> {
    pub lexeme: &'a str,
    pub line: u32,
    pub kind: TokenType,
}

Represents a single token in the source code

Fields

lexeme: &'a str

The actual text of the token

line: u32

The line number where the token appears

kind: TokenType

The type of the token

Implementations

impl<'a> Token<'a>

pub fn new(kind: TokenType, origin: &'a str, line: u32) -> Self

Creates a new token with the given type, text, and line number

pub fn is_function_def_keyword(&self) -> bool

pub fn is_error_type(&self) -> bool

pub fn is_literal_token(&self) -> bool

pub fn is_synchronize_keyword(&self) -> bool

pub fn is_expr_start(&self) -> bool

Check if the token could start as an expression.

Trait Implementations

impl<'a> Clone for Token<'a>

fn clone(&self) -> Token<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Token<'a>

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

Formats the value using the given formatter.

impl Default for Token<'_>

fn default() -> Self

Returns the “default value” for a type.

impl<'a> Hash for Token<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for Token<'a>

fn eq(&self, other: &Token<'a>) -> 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.
