Hi Pedro. Bare Rust already works in UEFI. In fact, UEFI support for 
no_std Rust has been present upstream for a few years. However, as you 
might be able to guess, bare Rust without any allocation and use of 
external crates simply did not provide enough benefits over C to migrate 
older projects to it. Additionally, without std, it's difficult to do 
enough significant testing to generate enough confidence in a new 
language like this.

Also to clarify, using Rust std in an application does not mean the 
whole std will be bundled with the application. Only the parts of std 
that are actually used by the application will be bundled in the final 
binary.

You can find more information about what is already present in upstream 
Rust for UEFI here: 
https://doc.rust-lang.org/nightly/rustc/platform-support/unknown-uefi.html

There is also some talks about promoting UEFI target to Tier-2, and 
having an std implementation will certainly help with that.


Yours Sincerely.

Ayush Singh
