# Function futures::future::result [−] [src]

    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 `finished` and `failed` base future types to convert an immediate value to a future to interoperate elsewhere.

# Examples

    use futures::future::*;

    let future_of_1 = result::<u32, u32>(Ok(1));
    let future_of_err_2 = result::<u32, u32>(Err(2));

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
