通过ThreadsafeFunction的call方法可以调用到传入的 JS 回调函数,但是我们会发现它拿不到返回值,如果我们需要获取到 JS 回调函数的返回值时,我们需要使用call_with_return_value和call_async两个方法。 获取JS 函数的返回值 对比call与call_with_return_value的实现可以看出,call_with_return_value比call多一个回调函数...

async 其实一般很少直接去实现Future trait, 直接使用async去自动实现Future trait就足够了。上边Delay完全可以这么实现,简洁且高效 代码语言:javascript 复制 use std::sync::Arc;use std::thread;use std::time::{Duration,Instant};use tokio::sync::Notify;asyncfndelay(dur:Duration){letwhen=Instant::now()...

Introduction - Rust异步运行时基础部件toetoe55.github.io/async-rt-book/ Future 我们还是得从Future讲起,Future是rust中异步编程的最基础的抽象,表示一个异步的计算。 Future的接口 Future的接口采用的是基于轮询的形式,而非更加常见的CPS形式: 为了方便叙述,这里先去掉一些噪音,化简了一下现有接口 ...
