Function futures::failed

pub fn failed<T, E>(e: E) -> Failed<T, E> where T: Send + 'static, E: Send + 'static

Creates a "leaf future" from an immediate value of a failed computation.

The returned future is similar to done where it will immediately run a scheduled callback with the provided value.

Examples

use futures::*;

let future_of_err_1 = failed::<u32, u32>(1);
