Yeah, Rust's musl support is great. We use it heavily at work for all sorts of CLI tools. Many thanks to everybody who worked on this.

(And if you need to link against common C libraries like OpenSSL or PostgreSQL, I maintain a Docker image with the necessary C toolchains, and instructions on how to use it: https://github.com/emk/rust-musl-builder. There are a couple of similar images out there, too, I think.)

You can also download the cross-compilation tarball for musl at https://static.rust-lang.org/dist/rust-std-1.31.0-x86_64-unk... if you installed rust that way. You'd then build normally:

    $ cargo build --target x86_64-unknown-linux-musl
