Struct SourcePos

pub struct SourcePos {
    pub byte: usize,
    pub line: usize,
    pub col: usize,
}

Indicates a character/token position in the original source.

Fields

byte: usize

The byte offset since the start of parsing.

line: usize

The line offset since the start of parsing, useful for error messages.

col: usize

The column offset since the start of parsing, useful for error messages.

Implementations

impl SourcePos

pub fn new() -> SourcePos

Constructs a new, starting, source position

pub fn advance(&mut self, next: &Token)

Increments self using the length of the provided token.

Trait Implementations

impl Clone for SourcePos

fn clone(&self) -> SourcePos

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SourcePos

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

Formats the value using the given formatter.

impl Default for SourcePos

fn default() -> Self

Returns the “default value” for a type.

impl Display for SourcePos

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

Formats the value using the given formatter.

impl PartialEq for SourcePos

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

impl Copy for SourcePos

impl Eq for SourcePos
