Comparison & Conversion

Equality

if (id1.eql(id2)) {
    std.debug.print("UUIDs are equal\n", .{});
}

Ordering

const order = id1.compare(id2); // .lt, .eq, .gt

Byte Conversion

// To bytes
const bytes = id.toBytes(); // [16]u8

// From bytes
const id = uuid.UUID.fromBytes(bytes);

Integer Conversion

// To u128
const int_val = id.toU128(); // u128

// From u128
const id = uuid.UUID.fromU128(int_val);

Hashing

const hash_val = id.hash(); // u64

Useful for hash maps:

var map = std.AutoHashMap(uuid.UUID, Value).init(allocator);
try map.put(id, value);

Version & Variant Inspection

const version = id.version();   // .v1, .v3, .v4, .v5, .v6, .v7, .v8, .nil, .unknown
const variant = id.variant();   // .ncs, .rfc, .microsoft, .future
const is_nil = id.isNil();      // true/false
