pub struct Captures<'t> { /* private fields */ }
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.

Returns the number of captured groups.

Returns true if and only if there are no captured groups.

Creates an iterator of all the capture groups in order of appearance in the regular expression.

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.

Offset of the captures within the given string slice.
