Struct codespan::ColumnIndex

pub struct ColumnIndex(pub RawIndex);

A zero-indexed column offset into a source file

Implementations

impl ColumnIndex

pub const fn number(self) -> ColumnNumber

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

use codespan::{ColumnIndex, ColumnNumber};

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

pub const fn to_usize(self) -> usize

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