calyx 0.1.1

//! Internal representation for the Calyx compiler.
//!
//! The representation is generated from the frontend AST.
//! The key differences between the frontend AST and the IR are:
//! 1. The IR uses pointers instead of [`Id`] to refer to things like [`Port`] and
//!    [`Group`].
//! 2. The IR attempts to represent similar concepts in a homogeneous manner.
