hex

Hexadecimal encoding and decoding for Quadrate.

Installation

quadpm install https://github.com/quadrate-language/hex

Usage

use hex

fn main() {
    // Encode to uppercase hex
    "Hello" hex::encode -> h
    h print nl  // "48656C6C6F"

    // Encode to lowercase hex
    "Hello" hex::encode_lower -> h2
    h2 print nl  // "48656c6c6f"

    // Decode hex string
    "48656C6C6F" hex::decode -> s
    s print nl  // "Hello"

    // Single byte operations
    65 hex::encode_byte -> b
    b print nl  // "41"

    "41" hex::decode_byte -> v
    v print nl  // 65

    // Validation
    "48656C6C6F" hex::is_valid -> valid
    valid print nl  // 1
}
