Struct `LocalFutureObj`

struct LocalFutureObj<'a, T> { ... }

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.

Implementations

`impl<'a, T> LocalFutureObj<'a, T>`

fn new<F: UnsafeFutureObj<'a, T> + 'a>(f: F) -> Self

Create a LocalFutureObj from a custom trait object representation.

unsafe fn into_future_obj(self: Self) -> FutureObj<'a, 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.
