This is specific to our project, but you will need one last tool, `cargo2nix`.
To install it, run:
```bash
cargo install --git https://github.com/superboum/cargo2nix --branch main cargo2nix
```
You must use it every time you modify a `Cargo.toml` or regenerate a `Cargo.lock` file as follow:
```bash
cargo build # Rebuild Cargo.lock if needed
cargo2nix -f
```
It will output a `Cargo.nix` file which is a specific `Cargo.lock` file dedicated to Nix that is required by our CI
which means you must include it in your commits.
Later, to use our scripts and integration tests, you might need additional tools.
These tools are listed at the end of the `shell.nix` package in the `nativeBuildInputs` part.
It is up to you to find a way to install the ones you need on your computer.

## Quirks about cargo2nix/rust in Nix
If you use submodules in your crate (like `crdt` and `replication` in `garage_table`), you must list them in `default.nix`
The Windows target does not work. it might be solvable through [overrides](https://github.com/cargo2nix/cargo2nix/blob/master/overlay/overrides.nix). Indeed, we pass `x86_64-pc-windows-gnu` but mingw need `x86_64-w64-mingw32`
We have a simple [PR on cargo2nix](https://github.com/cargo2nix/cargo2nix/pull/201) that fixes critical bugs but the project does not seem very active currently. We must use [my patched version of cargo2nix](https://github.com/superboum/cargo2nix) to enable i686 and armv6l compilation. We might need to contribute to cargo2nix in the future.
## Nix
Nix has no armv7 + musl toolchains but armv7l is backward compatible with armv6l.
