# nu-pretty-hex
An update of prett-hex to make it prettier

A Rust library providing pretty hex dump.
A `simple_hex()` way renders one-line hex dump, 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()`
```rust
use pretty_hex::*;
let v = vec![222, 173, 190, 239, 202, 254, 32, 24];
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()`
```rust
use pretty_hex::*;
let v: &[u8] = &random::<[u8;30]>();
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()`
```rust
use pretty_hex::*;
let cfg = HexConfig {title: false, width: 8, group: 0, ..HexConfig::default() };
let v = &include_bytes!("data");
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..
```
