[−][src]Struct grep_matcher::NoCaptures
NoCaptures provides an always-empty implementation of the Captures
trait.
This type is useful for implementations of Matcher
that don't support
capturing groups.
Methods
impl NoCaptures
[src]
pub fn new() -> NoCaptures
[src]
Create an empty set of capturing groups.
Trait Implementations
impl Captures for NoCaptures
[src]
fn len(&self) -> usize
[src]
fn get(&self, _: usize) -> Option<Match>
[src]
fn is_empty(&self) -> bool
[src]
Returns true if and only if these captures are empty. This occurs when len
is 0

[src]
&self,
name_to_index: F,
haystack: &[u8],
replacement: &[u8],
dst: &mut Vec<u8>
) where
F: FnMut(&str) -> Option<usize>,
Expands all instances of $name
in replacement
to the corresponding capture group name
, and writes them to the dst
buffer given. Read more
