Trait FutureExt

pub trait FutureExt: Future {
    // Provided method
    fn and_then2<F, B>(self, f: F) -> AndThen2<Self, B::Future, F>
       where B: IntoFuture,
             F: FnOnce(Self::Item) -> B,
             Self: Sized { ... }
}

An extension trait that provides a convenient method and_then2.

Provided Methods

fn and_then2<F, B>(self, f: F) -> AndThen2<Self, B::Future, F>

where B: IntoFuture, F: FnOnce(Self::Item) -> B, Self: Sized,

Creates a future object that resolves into an item that contains a Result of a computation of the provided closure f.

It is very similar to a traditional Future::and_then, but differs in an item’s type.

Might come in handy when you have futures with different error types and you don’t want to collect them into an enum.
