Struct hex_utils::Options

pub struct Options {
    pub size: usize,
    pub pack: Vec<usize>,
    pub dot: char,
}

Options how to create xxd output.

Fields

size: usize

how many bytes per line

pack: Vec<usize>

how to pack xx bytes next to each other (each value in vec, will put space every that byte)

dot: char

standard xxd will print '.' for non printable char, here you can change it.

Methods

impl Options

fn default() -> Option<Options>

Create default options

Examples

extern crate hex_utils;

let options = hex_utils::Options::default().unwrap();

assert_eq!(16, options.size);

fn or_default(options: Option<Options>) -> Options

Get the options out of Option or get the default ones.

Examples

let options = Some(hex_utils::Options { size: 9, pack: vec![3,5], dot: '#' });

let opt = hex_utils::Options::or_default(options);
assert_eq!(9, opt.size);
assert_eq!(vec![3,5], opt.pack);
assert_eq!('#', opt.dot);

let opt = hex_utils::Options::or_default(None);
assert_eq!(16, opt.size);
assert_eq!(vec![2,4,8], opt.pack);
assert_eq!('.', opt.dot);

fn formatter(&self) -> Box<Fn((usize, String, Option<String>)) -> String>

Format the xxd output based on these options.
