Webb12 maj 2024 · thread::spawn accepts a synchronous closure, whereas task::spawn accepts a future, and an async block is a future.

That would look like thread::spawn ( block_on (async { ... })). … WebbWe have now seen an end-to-end example of how asynchronous Rust works. Rust's async/await feature is backed by traits. This allows third-party crates, like Tokio, to provide the execution details. Asynchronous Rust operations are lazy and require a caller to poll them. Wakers are passed to futures to link a future to the task calling it. is there a problem with roku https://calderacom.com

Webbでは、なぜspawn()がJoinHandleを返すのか（つまり根本原因は何か）というと、Rustのasyncブロック（async { }）やasync関数（async fn() {}）は糖衣構文になっており、実際には戻り値型の値を直接返すのではなくて、戻り値型をfutureで包んだものを返すからです。 WebbTokio is fast, gos runtime is also quite fast. The benchmarks mentioned about async rust being slower are from a bad implementation from someone who had never programed much rust before. You can write any program in any language to be slow. It is unlikely that go would be much faster if it is at all.
