This reminded me of ATS - http://www.ats-lang.org/ Check also Chris Double blog - http://bluishcoder.co.nz/tags/ats/

ATS combines ML-style types, linear types, dependent types and theorem-proving. Plus it compiles down to C, has pointers including (safe!) pointer arithmetic, has trivial C interop, and doesn't have GC (alloc/free safety is provided by the linear types, like with Rust lifetimes). It's a really interesting beast and I hope I have more time in the future to dive into it. Idris wins in the syntax department tho.

Rust's move/ownership semantics are based on linear types, where as its lifetimes are based on regions. ATS has linear types, but not regions.
