UUIDv7Generator

final class UUIDv7Generator extends AnyRef

Generator for UUIDv7 as defined in RFC 9562. https://www.rfc-editor.org/rfc/rfc9562.html

UUIDv7 is a time-ordered UUID that embeds a Unix timestamp in milliseconds.

Monotonicity is best-effort but not strictly guaranteed by this implementation, in rare cases such as concurrent generation within the same millisecond or clock adjustments. This trade-off is intentional to avoid throughput degradation or thread contention.
