Struct esparse::ast::Loc

pub struct Loc {
    pub pos: usize,
    pub row: usize,
    pub col: usize,
}

A location in source code.

Stores both the bytewise position and the logical line and character numbers.

Fields

pos: usize

0-based byte index.

row: usize

0-based line number.

col: usize

0-based character number on the line.

Methods

impl Loc

fn new(pos: usize, row: usize, col: usize) -> Self

Creates a new Loc with the given positions.

fn zero() -> Self

Creates a new Loc pointing to the first byte of the source code (pos, row, and col all zero).
