//! This crate provides various common gadgets and chips for use with `halo2_proofs`.
//!
//! # Gadgets
//!
//! Gadgets are an abstraction for writing reusable and interoperable circuit logic. They
//! do not create any circuit constraints or assignments themselves, instead interacting
//! with the circuit through a defined "instruction set". A circuit developer uses gadgets
//! by instantiating them with a particular choice of chip.
//!
//! # Chips
//!
//! Chips implement the low-level circuit constraints. The same instructions may be
//! implemented by multiple chips, enabling different performance trade-offs to be made.
//! Chips can be highly optimised by their developers, as long as they conform to the
//! defined instructions.
