There are executors for more specific use cases.
bastionis a "Highly-available Distributed Fault-tolerant Runtime", inspired by Erlang, and including an async executor.embassyincludes an async executor specifically for embedded systems.fuchsia-asyncis an executor for use in the Fuchsia OS.wasm-bindgen-futuresconverts RustFutures to JavaScriptPromises and schedules them to run to completion. It could also be seen as a (very basic) executor.I think gtk-rs is another interesting example. The
glibcrate provides an async executor, since glib already requires running its main loop. So if you just need to run a couple futures you don't need another executor in one or more other threads, and tasks spawned in the glib executor can call functions that need to be run in that thread, since gtk types are generally not thread safe.So integrating into other things could be a reason to use a different executor..
