[][src]Struct actix_web::actix::fut::StreamThen

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

A stream combinator which chains a computation onto each item produced by a stream.

This structure is produced by the ActorStream::then method.
