Struct TryCapturesIter
pub struct TryCapturesIter<'h, F> { /* private fields */ }An iterator over all non-overlapping captures for a fallible search.
The iterator yields a Result<Captures, MatchError> value until no more
matches could be found.
The type parameters are as follows:
Frepresents the type of a closure that executes the search.
The lifetime parameters come from the Input type:
'his the lifetime of the underlying haystack.
When possible, prefer the iterators defined on the regex engine you're using. This tries to abstract over the regex engine and is thus a bit more unwieldy to use.
This iterator is created by Searcher::into_captures_iter.
Implementations
impl<'h, F> TryCapturesIter<'h, F>
fn infallible(self) -> CapturesIter<'h, F>Return an infallible version of this iterator.
Any item yielded that corresponds to an error results in a panic. This is useful if your underlying regex engine is configured in a way that it is guaranteed to never return an error.
