Struct Captures 

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

A set of captured substrings from a single match

Implementations

impl<'t> Captures<'t>

pub fn new(text: &'t str, full_match: (usize, usize), num_groups: usize) -> Self

Create a new Captures with the full match

pub fn get(&self, index: usize) -> Option<&'t str>

Get the matched substring for a capture group

Index 0 returns the full match, indices 1+ return capture groups

pub fn pos(&self, index: usize) -> Option<(usize, usize)>

Get the position (start, end) of a capture group

pub fn as_str(&self) -> &'t str

Get the full matched text (equivalent to get(0))

pub fn len(&self) -> usize

Number of capture groups (including the full match at index 0)

pub fn is_empty(&self) -> bool

Check if there are no capture groups

pub fn iter(&self) -> CapturesIter<'_, 't>

Iterate over all captured substrings

Trait Implementations

type Output = str

The returned type after indexing.

fn index(&self, index: usize) -> &Self::Output

Performs the indexing (container[index]) operation.
