Could this allow for developing a toy kernel in Rust as long as you define those few libc functions (maybe even with e.g. musl[1])? [1]: http://www.musl-libc.o

It's tempting to just say "yes". Tool support is not yet good enough. Inline assembly is available. Language constructs allow for deterministic memory allocation patters. https://github.com/mozilla/rust/pull/5317 https://github.com/mozilla/rust/pull/5317

It's not obvious to me you can write to memory at arbitrary memory locations, which is usually a requirement for writing a kernel.

  You can: unsafe { *(123 as *mut uint) = 4567; }

  There is always Assembly as well.
