//! This crate offers elliptic curves types which are compatible with the
//! [Arkworks](https://github.com/arkworks-rs) library functionalities.
//!
//! The implementation has been primarily designed to be used in slow hosted
//! targets (e.g. wasm32) and offloads the most computationally expensive
//! operations to the host by leveraging the
//! [arkworks-extensions](https://github.com/paritytech/arkworks-extensions)
//! library and Substrate's host functions.
//!
//! The exported types are organized and named in a way that mirrors the structure
//! of the types in the original Arkworks library. This design choice aims to make
//! it easier for users already familiar with the library to understand and utilize
//! the exported types effectively.
