Description
Thank you for building hermit; I hope this will become a conerstone of rust infrastructure soon!
At Rosenpass (post quantum security for WireGuard in Rust) we are currently exploring using broker based security sandboxing. As part of this project we are trying to add experimental support for running significant parts of the Rosenpass deployment inside Hermit OS.
The core rosenpass process uses mio to handle IO operations to enable the use of async io. We are considering eventually migrating to tokio.
Building hermit-rs-template with --target x86_64-unknown-hermit and a dependency on mio without non-default features yields a successful build. Adding the net feature yields a whole bunch of compile time errors (log).
Is using mio expected to work?
