Hi there, I have been trying out Rust with Bazel for while now and must say the experience is quite nice.

I want to start developing firmware utilities with Rust and Bazel. I'm trying to target the UEFI platform for now. I see there is a way to register toolchains for Rust inside Bazel, but it keeps giving me errors. The target triple I'm going for is x86_64-unknown-uefi but it keeps on throwing an error that it's not supported.

Is it possible to develop bare metal targets with rules_rust?

The full error log is below:

Hi,

Sorry for answering so late. Glad you are looking into that. We have a bunch of bindings here that defines the mapping between rust platform and various other property. uefi is unknown so either you need to update the system or (most probably) add it to the triple_mappings.
