//! Utility types and enums

//! This module contains helper types.
//! This module contains various helper types. This includes wrapper for primitive rust types
//! using the newtype pattern. This was also done for pairs and triplets of these primtive types.
//!
//! The [ToBeBytes] was implemented for those types as well, which allows to easily convert them
//! into a network friendly raw byte format.
//!
//! The module also contains generic parameter enumerations.
//!
//! # Example for primitive type wrapper
//!
//! ```
//! use fsrc_core::util::{ParamsRaw, ToBeBytes, U32Pair};
