Struct regex::Matches

pub struct Matches<'r, 't>(_);

An iterator over all non-overlapping matches for a particular string.

The iterator yields a Match value. The iterator stops when no more matches can be found.

'r is the lifetime of the compiled regular expression and 't is the lifetime of the matched string.
