## What is this? `dependent-ghost` is a library that provides some of the benefits of dependent typing to Rust via the [Ghosts of Departed Proofs](https://kataskeue.com/gdp.pdf) technique. Library authors can provide APIs with statically-checked preconditions and invariants, which the *user* can validate however necessary. All credit for this technique goes to Matt Noonan, the author of the original paper.
