Struct At 

pub struct At {
    pub line: usize,
    pub column: usize,
}

Where in the source something is, counted from one as an editor counts.

Fields

line: usize

Line, from 1.

column: usize

Column, from 1.

Implementations

impl At

pub const START: Self

The start of the file, for a complaint about the file as a whole.

pub fn of(source: &str, offset: usize) -> Self

The position of a byte offset in source.

Computed on demand rather than carried around: the parser hands back byte spans, and a form that loads without complaint should not have paid for counting newlines.

let source = "form \"F\" version=1\n    label \"æøå\" x=0\n";

assert_eq!(At::of(source, 0), At { line: 1, column: 1 });
// Characters, not bytes, so a column points where a caret would be even
// on a line with an `æ` in it.
assert_eq!(At::of(source, source.len() - 1).line, 2);
