CaptureLocations is a low level representation of the raw offsets of each submatch.
You can think of this as a lower level
Captures, where this type does not support
named capturing groups directly and it does not borrow the text that these
offsets were matched on.
Primarily, this type is useful when using the lower level
read_captures, 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.
Returns the start and end positions of the Nth capture group. Returns
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 string matched.
Returns the total number of capturing groups.
This is always at least
1 since every regex has at least
capturing group that corresponds to the entire match.
