@ExperimentalUnsignedTypes
fun fromUByteArray(ubyteArray: UByteArray): Uuid(source)

Creates a uuid from an array containing 128 bits split into 16 unsigned bytes.

Each unsigned byte in the ubyteArray sequentially represents the next 8 bits of the uuid, starting from the most significant 8 bits in the first byte to the least significant 8 bits in the last byte.

Since Kotlin

2.1
