#1755 introduces a new implementation of the compatibility layer that pushes it into Rust and wraps quil-rs directly. This addresses both API consistency and performance issues of the existing compatibility layer. See the description of #1755 for details of the proposal.

This milestone tracks all the work items that are needed for this new backend to reach feature parity with the existing backend. When this milestone is complete, users should be able to use the new backend without compromising anything from the existing backend.
