// #![no_std]

//! A Rust library providing pretty hex dump.
//!
//! A `simple_hex()` way renders one-line hex dump, and a `pretty_hex()` way renders
//! columned multi-line hex dump with addressing and ASCII representation.
//! A `config_hex()` way renders hex dump in specified format.
//!
//! ## Example of `simple_hex()`
//! ```
//! use pretty_hex::*;
//!
//! let v = vec![222, 173, 190, 239, 202, 254, 32, 24];
//! # #[cfg(feature = "alloc")]
//! assert_eq!(simple_hex(&v), format!("{}", v.hex_dump()));
//!
//! println!("{}", v.hex_dump());
//! ```
//! Output:
//!
//! ```text
//! de ad be ef  ca fe 20 18
//! ```
//! ## Example of `pretty_hex()`
//! ```
//! use pretty_hex::*;
//!
//! let v = &include_bytes!("../tests/data");
//! # #[cfg(feature = "alloc")]
//! assert_eq!(pretty_hex(&v), format!("{:?}", v.hex_dump()));
//!
//! println!("{:?}", v.hex_dump());
//! ```
//! Output:
//!
//! ```text
//! Length: 30 (0x1e) bytes
//! 0000:   6b 4e 1a c3  af 03 d2 1e  7e 73 ba c8  bd 84 0f 83   kN......~s......
//! 0010:   89 d5 cf 90  23 67 4b 48  db b1 bc 35  bf ee         ....#gKH...5..
//! ```
//! ## Example of `config_hex()`
//! ```
//! use pretty_hex::*;
//!
//! let cfg = HexConfig {title: false, width: 8, group: 0, ..HexConfig::default() };
//!
//! let v = &include_bytes!("../tests/data");
//! # #[cfg(feature = "alloc")]
//! assert_eq!(config_hex(&v, cfg), format!("{:?}", v.hex_conf(cfg)));
//!
//! println!("{:?}", v.hex_conf(cfg));
//! ```
//! Output:
//!
//! ```text
//! 0000:   6b 4e 1a c3 af 03 d2 1e   kN......
//! 0008:   7e 73 ba c8 bd 84 0f 83   ~s......
//! 0010:   89 d5 cf 90 23 67 4b 48   ....#gKH
//! 0018:   db b1 bc 35 bf ee         ...5..
