Overview

Delay (delayed execution), executes a closure function after a certain period of time to handle asynchronous operations.

Basic usage

\Co\delay(function () {
    echo 'delay task';
}, 1);

\Co\sleep(10); // Suspend the main process for 10 seconds so that other coroutines can complete the task

hint

In the scaffolding provided by ripple, most framework controller requests will occur in the async space. You can use the \Co\delay method in the controller.
