# tarpit-rs: Smallfuck implemented in Rust's type system

I wrote a blog post on this! You can find it

[here](https://sdleffler.github.io/RustTypeSystemTuringComplete/).

This is a proof of the Turing-completeness of Rust's type system; it's an

implementation of [Smallfuck](https://esolangs.org/wiki/Smallfuck), a known

Turing complete language. Since Rust's type system may have a Turing-complete

language embedded in it, we know therefore it must be Turing-complete itself!

Neat.

Contained in this repository are both the type-level implementation *and* a

minimal, unoptimized runtime implementation for verifying the type-level

implementation. Additional tests can be added via the `sf_test!{}` macro, and

run using `cargo test`.
