You can find it\n[here](https://sdleffler.github.io/RustTypeSystemTuringComplete/).\n\nThis is a proof of the Turing-completeness of Rust's type system; it's an\nimplementation of [Smallfuck](https://esolangs.org/wiki/Smallfuck), a known\nTuring complete language. Since Rust's type system may have a Turing-complete\nlanguage embedded in it, we know therefore it must be Turing-complete itself!\nNeat.\n\nContained in this repository are both the type-level implementation *and* a\nminimal, unoptimized runtime implementation for verifying the type-level\nimplementation. Additional tests can be added via the `sf_test!{}` macro, and\nrun using `cargo test`.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsdleffler%2Ftarpit-rs","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsdleffler%2Ftarpit-rs","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsdleffler%2Ftarpit-rs/lists"}
