# What you need to write low level Rust code

* do not use cargo, use rustc directly to build your code
* you need to use a target.json file describing your target platform (example: https://github.com/hackndev/zinc/blob/master/thumbv6-none-eabi.json ). Pass it to rustc via --target=target.json
* you wan work without the standard library, by following those instructions: https://doc.rust-lang.org/book/no-stdlib.html
*
