Struct grep_matcher::NoCaptures
source · pub struct NoCaptures(/* private fields */);
Expand description
NoCaptures provides an always-empty implementation of the Captures
trait.
This type is useful for implementations of Matcher
that don’t support
capturing groups.
Implementations§

impl NoCaptures
sourcepub fn new() -> NoCaptures
pub fn new() -> NoCaptures
Create an empty set of capturing groups.

source§fn len(&self) -> usize
fn len(&self) -> usize
Return the total number of capturing groups. This includes capturing
groups that have not matched anything.
source§fn get(&self, _: usize) -> Option<Match>
fn get(&self, _: usize) -> Option<Match>
Return the capturing group match at the given index. If no match of
that capturing group exists, then this returns
None
