Struct AttachedFuture

pub struct AttachedFuture<F, T> {
    inner: F,
    item: Option<T>,
}

Attach an item of type T to the future F. When the future is polled with ready, the item will be attached to the output of future as (F::Output, item).

The generated future will be similar to future.map(|output| (output, item)). The only difference is that the Map future does not provide method into_inner to get the original inner future.

Fields

inner: F

item: Option<T>

Trait Implementations

impl<F: Future + Unpin, T: Unpin> Future for AttachedFuture<F, T>

type Output = (<F as Future>::Output, T)

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
