[−][src]Struct pcre2::bytes::CaptureLocations
CaptureLocations is a low level representation of the raw offsets of each submatch.
Primarily, this type is useful when using Regex
APIs such as
captures_read
, which permits amortizing the allocation in which capture
match locations are stored.
In order to build a value of this type, you'll need to call the
capture_locations
method on the Regex
being used to execute the search.
The value returned can then be reused in subsequent searches.
Methods
impl CaptureLocations
[src]
pub fn get(&self, i: usize) -> Option<(usize, usize)>
[src]
Returns the start and end positions of the Nth capture group.
This returns None
if i
is not a valid capture group or if the
capture group did not match anything.
The positions returned are always byte indices with respect to the original subject string matched.
pub fn len(&self) -> usize
[src]
Returns the total number of capturing groups.
This is always at least 1
since every regex has at least 1
capturing group that corresponds to the entire match.
