```
public class FutureCallback
extends Object
```
A callback which is called when a [`Future`] completes. Note that this MUST NOT call back into LDK directly, it must instead schedule actions to be taken later. Rust users should use the [`std::future::Future`] implementation for [`Future`] instead. Note that the [`std::future::Future`] implementation may only work for runtimes which schedule futures when they receive a wake, rather than immediately executing them.
