Struct codespan::LineIndex

pub struct LineIndex(pub RawIndex);

A zero-indexed line offset into a source file

Implementations

impl LineIndex

pub const fn number(self) -> LineNumber

The 1-indexed line number. Useful for pretty printing source locations.

use codespan::{LineIndex, LineNumber};

assert_eq!(format!("{}", LineIndex(0).number()), "1");
assert_eq!(format!("{}", LineIndex(3).number()), "4");

pub const fn to_usize(self) -> usize

Convert the index into a usize, for use in array indexing
