Example

import hex

pub struct Person {
    age int
    name string
    gender Gender
    eye_color string
    hair_color string
    weight u16
}

enum Gender {
    male
    female
}

fn main() {
    str := 'V is awesome'
    println('SOURCE: ${str}')
    println('ENCODED: ${hex.encode(str)}')
    println('DECODED: ${hex.decode(hex.encode(str)) or {"failed"}}')

    p := Person{21, 'Adam', .male, 'hazel', 'brown', 100}
    enc := hex.encode_struct(p) or { 'failed'.bytes() }
    println('STRUCT ENCODED: ${enc.bytestr()}')
    dec := hex.decode_struct<Person>(enc) or {
        println(err.msg())
        exit(0)
    }
    println('STRUCT DECODED: ${dec}')
}
