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.

Implementations§

Create a LocalFutureObj from a custom trait object representation.

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.
