Webb27 juli 2024 · Take for example "can fail" and "can be async": That's a lot of API surface for just a single method, and that problem multiplies across the entire API surface in the stdlib. We expect that once we start applying "keyword generics" to traits, we will be able to solve the sandwich problem. WebbAsync A similar approach can be used by including the tokio executor to make the main function asynchronous, retrieving the same information. In this example, tokio::main handles all the heavy executor setup and allows sequential code implemented without blocking until .await.

WebbAsync in Rust uses a Poll based approach, in which an asynchronous task will have three phases. The Poll phase. A Future is polled which results in the task progressing until a point where it can no longer make progress. We often refer to the part of the runtime which polls a Future as an executor. The Wait phase.
