Struct TokenPosition 

pub struct TokenPosition {
    pub offset: usize,
    pub line: usize,
    pub column: usize,
}

Token stream position for streaming tokenization

Fields

offset: usize

Byte offset in source

line: usize

Line number (1-based)

column: usize

Column number (1-based)

Implementations

impl TokenPosition

pub const fn new(offset: usize, line: usize, column: usize) -> Self

Create new position

pub const fn start() -> Self

Create position at start of input

pub const fn advance(self, ch: char) -> Self

Advance position by one character

pub fn advance_by_str(self, s: &str) -> Self

Advance position by string length

Trait Implementations

impl Clone for TokenPosition

fn clone(&self) -> TokenPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TokenPosition

impl Debug for TokenPosition

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

Formats the value using the given formatter.

impl Default for TokenPosition

fn default() -> Self

Returns the “default value” for a type.

impl Eq for TokenPosition

impl PartialEq for TokenPosition

fn eq(&self, other: &TokenPosition) -> 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.
