Struct CaptureLocations 

pub struct CaptureLocations { /* private fields */ }

Reusable capture-slot buffer — drop-in for [regex::CaptureLocations].

Obtain via Regex::capture_locations, refill with Regex::captures_read (or captures_read_at). Spans are read with get. The buffer is not tied to a text lifetime, so it can be reused across many subjects without allocating a Captures (or a group vector) per match.

Implementations

impl CaptureLocations

pub fn len(&self) -> usize

Number of capture slots, including group 0.

pub fn is_empty(&self) -> bool

Whether there are no capture slots (never true for a live Regex).

pub fn get(&self, i: usize) -> Option<(usize, usize)>

Byte offsets (start, end) of group i, or None if the group did not participate (or i is out of range).
