__disposeAsync
Note
This is a point-in-time snapshot of the API documentation from January 2026. Going forward, we will not be maintaining a public copy of these references, and recommend users to refer to the built-in signature helpers available in the Hack LSP instead for complete and up-to-date information.
This method is invoked exactly once at the end of the scope of the await using statement, unless the program terminates with a fatal error
public function __disposeAsync(): Awaitable<void>;
