UuidToString

Formats 16 raw bytes as a canonical UUID string.

Module: Std::UUID

Signature

func UuidToString(bytes: *const uint8, length: uint) -> String;

Parameters

Name	Type	Description
bytes	*const uint8	Pointer to the 16 UUID bytes.
length	uint	Number of bytes available; must be ≥ 16.

Returns

String — the canonical 36-character representation (xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx), or an empty string if length is less than 16.

Description

Renders raw UUID bytes as lowercase hex with hyphens. It does not interpret or validate the version/variant bits — it formats whatever bytes you pass.

Example

import Std::UUID;

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