Source language and Rust crate for FiTL. See the base readme or fitl.com for a more general overview on the language
Meant to be used as a standalone Rust library and core language for fitl, fitl-rs is also meant to be complilable for WebAssembly and Python (coming soon) with external wrapper libraries (see fitl-js).
Requirements:
- Rust >= 1.8
cargo build

cargo build --releaseT -> Generic Symbol (For below chart purposes only)
