# 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..
|
|
```
