chalk

A Prolog-ish interpreter written in Rust, intended perhaps for use in the compiler, but also for experimentation.

FAQ

How does chalk relate to rustc? The plan is to have rustc use the chalk-engine crate (in this repo), which defines chalk's solver. The rest of chalk can then be considered an elaborate unit testing harness. For more details, see the Traits chapter of the rustc-guide.

Where does the name come from? chalk is named after Chalkidiki, the area where Aristotle was born. Since Prolog is a logic programming language, this seemed a suitable reference.
