pub fn result<T, E>(r: Result<T, E>) -> FutureResult<T, E>
Creates a new "leaf future" which will resolve with the given result.
The returned future represents a computation which is finished immediately.
This can be useful with the
failed base future types to
convert an immediate value to a future to interoperate elsewhere.
use futures::future::*; let future_of_1 = result::<u32, u32>(Ok(1)); let future_of_err_2 = result::<u32, u32>(Err(2));
