Mustang update
Posted on
Mustang gained lots of new features recently. It's now complete enough to run lots of real-world Rust programs, with no libc:
- Tide's hello web server example (epoll and async!)
- Tokio's tinyhttp web server example (more epoll and async!)
- Most of coreutils (lots of stuff!)
- Ripgrep (threads!)
See here for instructions on how to port programs to mustang. And if you give it a try, post about your experience here, whether it works or not!
Looking ahead
Currently mustang requires programs be modified to include
mustang::can_run_this!() in their main source file, which is very inconvenient.
The only way I currently know how to fix that is to teach the Rust toolchain about
mustang. Is that the next step?
On one hand, mustang is cool and fun. But a lot of other things are cool and fun too. An official Rust toolchain would involve a lot of work from a lot of people who have a lot of other important things to work on. And for the most obvious use cases, one of the Musl targets would be a better choice, being more featureful and stable and so on.
So mustang is kind of waiting for a sign.
