[−][src]Struct futures_task::FutureObj
A custom trait object for polling futures, roughly akin to
Box<dyn Future<Output = T> + Send + '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.
You should generally not need to use this type outside of no_std or when
implementing Spawn, consider using BoxFuture instead.
