### impl<F> IntoFuture for F where
F: Future,

#### type Output = <F as Future>::Output

🔬 This is a nightly-only experimental API. (`into_future`)

The output that the future will produce on completion.

#### type IntoFuture = F

🔬 This is a nightly-only experimental API. (`into_future`)

Which kind of future are we turning this into?

source

#### fn into_future(self) -> <F as IntoFuture>::IntoFuture

🔬 This is a nightly-only experimental API. (`into_future`)

Creates a future from a value.
