Portable and Interoperable Async Rust

Re:Portable and Interoperable Async Rust by varajelle on Wednesday December 08, 2021 @10:45AM (#29486120)

The std::future::Future from the rust standard library works with every runtime.

Not sure I understand, what kind of interoperability you are talking about. What kinds of code works in C++ across runtimes, for which the equivalent in Rust doesn't?

In C++ you don't have the scenario like in Rust, where one is forced to use a specific async runtime for library xyz, because it depends on having tokio as runtime.

Or has that situation been sorted out by now?

In Rust you only are forced to use a specific runtime if you want to use its API. For example to spawn new tasks, or to block on a future. I believe that would be the same in C++.

In Rust, you don't need to use a specific runtime if you just want to use async function in your library.
