Rust with Emscripten

hello.rs

// emscripten uses le32-unknown-nacl triple but rustc doesn't know it now.
// So just use similar target instead.
// `rustc hello.rs --target=i686-unknown-linux --emit-llvm -S --cfg libc`
// `emcc hello.ll -o hello.js`

// no `extern mod`.
#[no_std];
#[feature(macro_rules)];
