### Design
All `crates`/`libraries` are in a `no-std` environment. This means we only have access to the [libcore](https://doc.rust-lang.org/core/) functionality.
However, we will be using the `alloc` crate to access the heap, and`collections` to have access to data structures like `Vec`.
## Learning
Before jumping in, I highly recommend learning some stuff abotu **Rust** and embedded developmend with it.
A thorough series of steps might be:
1. Read through the [Rust Book](https://doc.rust-lang.org/book/)
2. Work through the [Interactive Rust Book](https://rust-book.cs.brown.edu/)
3. Complete the [rustlings](https://github.com/rust-lang/rustlings) exercises
4. Take a quick look through the [Embedded Rust Book](https://docs.rust-embedded.org/book/intro/index.html)
