## Developing
### Set up
This is no different than other Rust projects.
```shell
git clone https://github.com/guapodero/perfume
cd perfume
cargo test
```
### Useful Commands
Be aware that there is an optional `nightly` feature which requires
[nightly rust](https://ehuss.github.io/rustup/concepts/channels.html#working-with-nightly-rust).
Some of the tests depend on generated code, which is why there is a `main.rs`.
- Run Clippy:
```shell
cargo clippy --all-targets -F codegen --workspace
```
- Run all tests:
```shell
cargo run -F codegen
TMPDIR=/tmp cargo test -F codegen --workspace
```
- Check to see if there are code formatting issues
```shell
cargo fmt --all -- --check
```
- Format the code in the project
```shell
cargo fmt --all
```
- Generate documentation (requires nightly channel)
```shell
RUSTDOCFLAGS="--cfg docsrs" cargo +nightly doc --no-deps --all-features
```
