Struct Token 

pub struct Token<'a> {
    pub token_type: TokenType,
    pub span: &'a str,
    pub line: usize,
    pub column: usize,
}

Token produced by ASS tokenizer with zero-copy span

Represents a lexical unit in ASS script with location information. The span references the original source text to avoid allocations.

Fields

token_type: TokenType

Token type discriminant

span: &'a str

Zero-copy span referencing source text

line: usize

Line number where token starts (1-based)

column: usize

Column number where token starts (1-based)

Implementations

impl<'a> Token<'a>

pub const fn new( token_type: TokenType, span: &'a str, line: usize, column: usize, ) -> Self

Create new token with full location information

pub fn len(&self) -> usize

Get token length in characters

pub const fn is_empty(&self) -> bool

Check if token is empty (should not happen in normal tokenization)

pub fn end_column(&self) -> usize

Get end column position

pub const fn is_whitespace(&self) -> bool

Check if this token represents whitespace

pub const fn is_delimiter(&self) -> bool

Check if this token represents a delimiter

pub const fn is_content(&self) -> bool

Check if this token represents content (text, numbers, etc.)

pub const fn validate_utf8(&self) -> bool

Validate that span references valid UTF-8

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 Display for Token<'_>

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

Formats the value using the given formatter.

impl<'a> Eq for Token<'a>

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.
