later
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.
Reschedule the work of an async function until some other time in the future
namespace HH\Asio;
function later(): Awaitable<void>;
The common use case for this is if your async function actually has to wait
for some blocking call, you can tell other Awaitables in the async
scheduler that they can work while this one waits for the blocking call to
finish (e.g., maybe in a polling situation or something).
Returns
Awaitable<void>-Awaitableofvoid.
