Phuture\Coherence\Enum\UuidVersion

enum UuidVersion

Enumeration for UUID generation version selection.

This enum defines the UUID versions available when generating unique identifiers. Use it with \Phuture\Coherence\Strings::uuid() to select which version to generate.

#Cases

#V4

case V4

Generate a version 4 UUID (random).

UUID v4 uses cryptographically secure random data for all bits except the version and variant fields. This is the most widely used UUID version and is suitable for generating unique identifiers without requiring coordination.

#V7

case V7

Generate a version 7 UUID (time-ordered).

UUID v7 combines a Unix timestamp in milliseconds with random data, producing identifiers that are both unique and sortable by creation time. The first 48 bits encode the timestamp, making these UUIDs naturally ordered chronologically.
