## development

you'll need a Rust toolchain and various system libraries.

you can obtain the former using `rustup` and the latter using `nix-shell`.
there's a `shell.nix` provided with the project.

from there, use the commands in the `Justfile`, e.g.:

```sh
just arranger
```

note that `tek > 0.2.0-rc.7` will require rust nightly
for the unstable features `type_alias_impl_trait` and
`impl_trait_in_assoc_type`. make some noise for lucky
[**rust rfc2515**](https://github.com/rust-lang/rust/issues/63063)
if you want to see this buildable with stable/beta.
