Struct wax::CapturingToken

pub struct CapturingToken { /* private fields */ }

Token that captures matched text in a glob expression.

Examples

CapturingTokens 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]);
}

Implementations

impl CapturingToken

pub fn index(&self) -> usize

Gets the index of the capture.

Captures are one-indexed and the index zero always represents the implicit capture of the complete match, so the index of CapturingTokens is always one or greater. See MatchedText.

pub fn span(&self) -> Span

Gets the span of the token’s sub-expression.
