Normal Description
The Rust language is gain some momentum as an alternative to C and C++ for embedded system (https://www.rust-lang.org/what/embedded) and it should be very useful to be able to develop NuttX applications using Rust language.
Sometime Yoshiro Sugino already ported the Rust standard libraries, but it was not a complete port and wasn't integrated on NuttX. Anyway this initial port could be used as starting point for some student willing to add official support on NuttX.
Also it needs to pave the way to support developing NuttX driver in Rust and an complement to C drivers.
