Struct futures::future::LocalFutureObj
source · [−]pub struct LocalFutureObj<'a, T> { /* private fields */ }
Expand description
A custom trait object for polling futures, roughly akin to
Box<dyn Future<Output = T> + 'a>
.
This custom trait object was introduced as currently it is not possible to
take dyn Trait
by value and Box<dyn Trait>
is not available in no_std
contexts.

where

Create a LocalFutureObj
from a custom trait object representation.

pub unsafe fn into_future_obj(self) -> FutureObj<'a, T>ⓘNotable traits for FutureObj<'_, T>impl<'_, T> Future for FutureObj<'_, T> type Output = T;
Converts the LocalFutureObj
into a FutureObj
.
Safety
To make this operation safe one has to ensure that the UnsafeFutureObj
instance from which this LocalFutureObj
was created actually
implements Send
.
