"Portable - Biscuit is implemented in Rust, Haskell, Go, Java, WebAssembly, C..."
but nothing about Javascript, NodeJS and Python, which seem very common these days.
In the case of NodeJS they're using WebAssembly to run the compiled Rust code, which is an interesting approach.
If they're just going to wrap the rust implementation, I'm surprised they haven't offered Ruby FFI or PHP FFI wrappers too.
