In this section, we'll cover the underlying structure of how Futures and asynchronous tasks are scheduled.If you're only interested in learning how to write higher-level code that uses existing Future types and aren't interested in the details of how Future types work, you can skip ahead to the async/await chapter.
Webb共享只读数据就是在多线程中，只能对变量进行读操作，不能进行写操作。 Rust是如何通过它的类型系统来保证数据共享的时候，只对数据进行只读操作呢？ 答案是Rust类型系统里面规定了，引用在任何时候只能是下面两种情况之一，而不能同时存在： Webb7 apr. 2024 · Regarding updating the waker in a race-free way, my suggestion is to use futures::task::AtomicWaker, which can store and wake a waker atomically.

WebbAs a runtime based on io_uring/epoll/kqueue, Monoio is designed to be the most efficient and performant thread-per-core Rust runtime with good platform compatibility. For some use cases, it is not necessary to make task schedulable between threads. For example, if we want to implement a load balancer like nginx, we may want to write it in a ... Webbasync code would be faster than synchronous code. Certainly never someone from the Rust team. async is less resource intensive in some settings (e.g. many sleeping connections or waiting tasks), but does not magically make code go brrr.
