[][src]Struct tokio::prelude::stream::Then

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

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

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