UuidV4Bytes

Generates a random version-4 UUID as raw bytes.

Module: Std::UUID

Signature

func UuidV4Bytes() -> String;

Returns

String — a 16-byte value holding the raw UUID bytes (with the version and variant bits set). Read the bytes with Data; the Length is always 16.

Description

Same generation as UuidV4, but returns the 16 binary bytes instead of the 36-character string. Convert to canonical text later with UuidToString.

WARNING

The randomness is not cryptographically secure — see the module overview.

Example

import Std::UUID;

let raw = UUID::UuidV4Bytes();          // 16 bytes
let text = UUID::UuidToString(raw.Data() as *const uint8, raw.Length());
