pub type Span = (usize, usize);
Expand description
Location and length of a token within a glob expression.
Spans are encoded as a tuple of usize
s, where the first element is the location or position
and the second element is the length. Both position and length are measured in bytes and
not code points, graphemes, etc.
Examples
Spans can be used to isolate sub-expressions.
use wax::Glob;
let expression = "**/*.txt";
let glob = Glob::new(expression).unwrap();
for token in glob.captures() {
let (start, n) = token.span();
println!("capturing sub-expression: {}", &expression[start..][..n]);
}
