esp-rs-nix

Project goals:

Take this: https://github.com/esp-rs/rust-build ...
...and this: https://github.com/espressif/crosstool-NG,
...and mangle them into a nix derivation (using hard-coded pre-built binaries for now).
Then, take this: https://github.com/esp-rs/esp-hal ...
... run nix-shell, and compile blinky for esp32s3.

Project status: works on my machine!

why?

The recommended installation method using the espup tool didn't work for me.

notes

This is for development of no_std, esp-hal-based applications only. NOT for use with esp-hal-idf.
This is hard-coded to download binaries for x86_64 only, at the moment.
PRs welcome!
