WebWith the tokio::main macro we can now make main async. The spawn function creates a new, concurrent “task”. Note: spawn takes a Future, you don’t call .await on count_to. Further exploration: Why does count_to not (usually) get to 10? This is an example of async cancellation. tokio::spawn returns a handle which can be awaited to wait ... WebThe difficulty with async trait is in that the resulting Future does not have a size known at compile time, because the size of the Future depends on the implementation. async_trait is easy to use, but note that it’s using heap allocations to achieve this, and solve the unknow size problem above. This heap allocation has performance overhead. WebDec 6, 2024 · tokio - An event-driven, non-blocking I/O platform for writing asynchronous applications.
