# rust workspace template
This is an experiment to contain the code for all components in a single repository, also known as a monorepository.
## Repository Layout
The code is grouped by language or framework name.
### Nix
```
/flake.nix
/flake.lock
/nix/ /* [blueprint](https://github.com/numtide/blueprint) set up underneath here. */
```
### Rust
```
/Cargo.toml
/Cargo.lock
/rust/ # all rust code lives here
/rust/common/Cargo.toml
