Struct futures_util::stream::Recover
[−]
[src]
#[must_use = "streams do nothing unless polled"]pub struct Recover<A, E, F> { /* fields omitted */ }
Future for the recover combinator, handling errors by converting them into
an Option<Item>, such that a None value terminates the stream. Recover
is compatible with any error type of the caller's choosing.
