What the Rust language and standard library take care of

Rust only provides what’s necessary to model asynchronous operations in the language. Basically, it provides the following:

  • A common interface that represents an operation, which will be completed in the future through the Future trait
  • An ergonomic way of creating tasks (stackless coroutines to be precise) that can be suspended and resumed through the async and await keywords
  • A defined interface to wake up a suspended task through the Waker type

That’s really what Rust’s standard library does. As you see there is no definition of non-blocking I/O, how these tasks are created, or how they’re run. There is no non-blocking version of the standard library, so to actually run an asynchronous program, you have to either create or decide on a runtime to use.
