Struct onig::Captures [−][src]
pub struct Captures<'t> { /* fields omitted */ }
Expand description
Captures represents a group of captured strings for a single match.
The 0th capture always corresponds to the entire match. Each subsequent index corresponds to the next capture group in the regex. Positions returned from a capture group are always byte indices.
't
is the lifetime of the matched text.
Implementations
Returns the start and end positions of the Nth capture group. Returns
None
if i is not a valid capture group or if the capture group did
not match anything. The positions returned are always byte indices with
respect to the original string matched.
Returns the matched string for the capture group i
. If i
isn’t
a valid capture group or didn’t match anything, then None
is returned.

impl<'t> Iterator for SubCapturesPos<'t> type Item = Option<(usize, usize)>;
Creates an iterator of all the capture group positions in order of appearance in the regular expression. Positions are byte indices in terms of the original string matched.
