Destroys a future object.

Returns true if the asynchronous result associated with this Future has a stored exception, false otherwise.

| std::logic_error | if this instance does not refer to a shared state. |
Returns true if the asynchronous result associated with this Future is ready (has a value or exception stored in the shared state), false otherwise.
There are often situations where a get() call on a Future may not be a blocking call, or is only a blocking call under certain circumstances. This method gives the ability to test for early completion and allows us to avoid associating a continuation, which needs to be scheduled with some non-trivial overhead and near-certain loss of cache efficiency.

Check if a future instance is associated with an asynchronous result.
Returns true if the *this has an associated asynchronous result, false otherwise.

Waits for the result to become available during the timeout.
- Note
- Calling
wait on the same Future from multiple threads is not safe; the intended use is for each thread that waits on the same shared state to have a copy of a Future.
