Future-powered I/O at the core of Tokio. The Future trait from this crate is conceptually similar to the version of the Future trait from the standard library but substantially different in details.async / await syntax is built around the version of the trait in the standard library. It also didn't help that I dove right in based on examples without reading much of the higher level documentation describing Futures. rustup is a convenient tool to install it, if you haven't already. rust documentation: Tokio-exempel. The GNU Proje Skip to content. [dependencies] warp = "0.2.0" When using async Rust, we also need to use an executor to poll Futures, so let's add a dependency on tokio to do that for us.tokio is already used by warp internally but we still need to explicity include it for our project. Just use a semaphore, dummy. However, the mini-redis tutorial that I linked above seems to cover everything that I would. tokio has been around for quite some time and it has seen extensive production usage.
