Decode

Decodes a hex slice back to bytes.

Module: Std::Hex

Signature

func Decode(hex: char8[]) -> String;

Parameters

Name	Type	Description
hex	char8[]	The hex text to decode.

Returns

String — the decoded bytes, packed into a String. Decoding an empty slice returns an empty string.

Description

Reverses Encode. Accepts both uppercase and lowercase hex digits. The returned String holds raw bytes, which may include zeros and need not be printable text.

WARNING

The input must have an even length, and every character must be a valid hex digit (0–9, a–f, A–F). Violations abort the program via Fatal. Validate untrusted input before decoding.

Example

import Std::Hex;

let bytes = Hex::Decode("527578");   // "Rux"
