std/uuid

UUIDs (RFC 9562), with random bits from the system.

import "std/uuid"

Uuid id = uuid7()
print(id.text())                       // 01936d3c-5a7e-7cc2-9f10-...
Uuid same = parse_uuid(id.text())?

Function or method	Result
`uuid4()`	a random UUID, version 4
`uuid7()`	a UUID of version 7: the time in milliseconds, a counter, and random bits, so those made later sort after, even within a millisecond
`nil_uuid()`	all zeros
`parse_uuid(text)`	the UUID text writes: with or without hyphens, in braces, or after `urn:uuid:`; an `ERROR` of kind `"invalid_uuid"` otherwise
`u.text()`, `u.version()`, `u.time_ms()`, `u.equals(other)`	its text, its version, when a version 7 UUID was made, and whether two are the same; `u.value` is its 16 bytes
