//! Provides traits for common functionality across several Rust BigInt implementations
//!
//! ## Example interaction:
//! ```
//! // import BigInt from this library. use a feature flag to select the BigInt you need
//! // also, pull one or more traits from this library into scope
//! use rust_bigint::BigInt;
//! use rust_bigint::traits::Converter;
//! 
//! let number = BigInt::from(42);
//! // now use one of the methods exposed by the converter trait
//! let hex_str = number.to_hex();
//! ```
//!
//! See the traits for more examples.
