1. Async Networking:Built-in support for TCP/UDP and HTTP. 2. Task Spawning:Run concurrent tasks with tokio::spawn. 3. Synchronization:Tools like Mutex and channels for shared state. 4. Timers:Asynchronous delays and periodic tasks with tokio::time. Best Practices 1. Selectively Enable Feature...
我观察到,在带async fn main注释的#[tokio::main](创建多线程运行时)中运行 async/await/join 代码会在同一线程中执行所有代码。在我开始通过 执行代码之前,我没有看到其他线程被使用tokio::spawn。 一些相关文档。 任务是调度程序管理的执行单元。生成任务会将其提交给 Tokio 调度程序,然后调度程序确保该任务在有...
block_in_place rt-multi-threadRuns the provided blocking function on the current thread without blocking the executor. spawn rtSpawns a new asynchronous task, returning a JoinHandle for it. spawn_blocking rtRuns the provided closure on a thread where blocking is acceptable. spawn_local rtSpawns ...
来执行待调度的 task, 以避免整个tokio runtime 完全 hang 住(有 task 但没 worker 运行它).
Async-scoped Enables controlled spawning of non-'static futures when using the async-std or tokio executors. Motivation Present executors (such as async-std, tokio, etc.) all support spawning 'static futures onto a thread-pool. However, they do not support spawning futures with lifetime smaller...
