method Deno.UnsafeCallback.threadSafe
UnsafeCallback.threadSafe<Definition extends UnsafeCallbackDefinition = UnsafeCallbackDefinition>(
definition: Definition,
callback: UnsafeCallbackFunction<Definition["parameters"], Definition["result"]>,
): UnsafeCallback<Definition>
Creates an [`UnsafeCallback`](../././~/Deno.UnsafeCallback) and calls `ref()` once to allow it to wake up the Deno event loop when called from foreign threads. This also stops Deno's process from exiting while the callback still exists and is not unref'ed.
