Struct alloc_data::Loc

pub struct Loc {
    pub file: Str,
    pub line: usize,
    pub span: Span,
}

A location.

Construction From String Slices

let s = "`blah/stuff/file.ml`:325:7-38";
let loc = Loc::parse(s).unwrap();
assert_eq! { format!("{}", loc), s }
assert_eq! { loc.file, "blah/stuff/file.ml" }
assert_eq! { loc.line, 325 }
assert_eq! { loc.span, (7, 38).into() }

Fields

file: Str

File the location is for.

line: usize

Line in the file.

span: Span

Column span at that line in the file.
