Struct Captures 

pub struct Captures<'s> { /* private fields */ }

Capture groups for one match. Group zero is the whole match.

Captures own their ranges and borrow only the input, so they may be retained after a scan callback returns. Groups are addressed by number.

Implementations

impl<'s> Captures<'s>

pub fn get(&self, index: usize) -> Option<Match<'s>>

Returns a participating group, or None for an unmatched or absent group.

pub fn len(&self) -> usize

Returns the number of capture groups, including group zero.

pub fn is_empty(&self) -> bool

Returns whether there are no groups. Successful matches include group zero.

pub fn iter(&self) -> impl ExactSizeIterator<Item = Option<Match<'s>>> + '_

Visits groups in numerical order, including nonparticipating groups.
