Struct futures::stream::OrElse [] [src]

#[must_use = "streams do nothing unless polled"]
pub struct OrElse<S, F, U> where
    U: IntoFuture
{ /* fields omitted */ }

A stream combinator which chains a computation onto errors produced by a stream.

This structure is produced by the Stream::or_else method.
