pub trait FutureExecutor: Executor { }Expand description
Marker trait for executors whose execution carrier is a future.
A FutureExecutor is still an Executor: it executes
Runnable and
Callable tasks through Executor::execute
and Executor::call.
Its distinguishing contract is that Self::Execution<R, E> should be a
future resolving to Result<R, E>.
Rust cannot currently express this contract for all R and E directly in
the trait definition, so implementations must document and uphold it.
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
