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

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

A stream which creates futures, polls them and return their result

This stream is returned by the futures::stream::unfold method
