Struct Captures 

pub struct Captures<'h>(/* private fields */);

A successful match and its capture groups.

Borrows the haystack, so it never escapes the call that produced it — MatchResult is the owned form that outlives a match.

Implementations

impl<'h> Captures<'h>

pub fn full(&self) -> &'h str

Text of the whole match (group 0).

pub fn start(&self) -> usize

Byte offset where the whole match begins. Non-zero whenever the leftmost match starts part-way into the haystack.

pub fn end(&self) -> usize

Byte offset just past the whole match — where the next search starts.

pub fn group_count(&self) -> usize

Number of groups, group 0 included; always at least 1.

pub fn groups(&self) -> impl Iterator<Item = Option<&'h str>> + '_

Every group in order, starting with group 0. None marks a group that did not participate in the match.
