ExecutorKeepAlive is a safe pointer to an Executor.
Synopsis
Declared in <folly/Executor.h>
template<typename ExecutorT = Executor>
class ExecutorKeepAlive;Description
For any Executor that supports keep‐alive functionality, its destructor will block until all the ExecutorKeepAlive objects associated with that executor are destroyed. For executors that don't support the keep‐alive functionality, ExecutorKeepAlive doesn't provide such protection.
ExecutorKeepAlive should always be used instead of Executor*. ExecutorKeepAlive can be implicitly constructed from Executor*.
The getKeepAliveToken() helper can be used to construct a keep‐alive in templated code if you need to preserve the original executor type.
