bf-rs: Brainfuck in Rust

bf-rs is a optimizing Brainfuck interpreter and JIT compiler inspired by Eli Bendersky’s series on JIT compilation. It includes a library crate bf that exports most of the functionality, and an executable bfi that provides a command-line interface for executing Brainfuck programs.

By default, installing bf does not enable the JIT compiler, because that requires nightly Rust. To build and install from crates.io with the JIT enabled:

$ rustup run nightly cargo install --features=jit bf
