com.vadelabs.uid.uuid.core — com.vadelabs/uid 2025.11.07-15

Core UUID generation and manipulation functions implementing RFC 9562.

Provides comprehensive support for all UUID versions (v0-v8) with efficient internal representation and conversion utilities.

Implementation inspired by clj-uuid by Dan Lentz: https://github.com/danlentz/clj-uuid Licensed under Eclipse Public License 1.0

+max+ clj

The MAX UUID is a special form of sentinel UUID that is specified to have all 128 bits set to one.

+namespace-dns+ clj

+namespace-oid+ clj

+namespace-url+ clj

+namespace-x500+ clj

+null+ clj

The NULL UUID is a special form of sentinel UUID that is specified to have all 128 bits set to zero.

< clj

(< _)

(< x y)

(< x y & more)

Directly compare two or more UUIDs for < relation.

= clj

(= _)

(= x y)

(= x y & more)

Directly compare two or more UUIDs for equality.

> clj

(> _)

(> x y)

(> x y & more)

Directly compare two or more UUIDs for > relation.

max clj

(max)

Generates the v15 (maximum) UUID.

monotonic-time clj

(monotonic-time)

Return a monotonic timestamp (guaranteed always increasing) based on the number of 100-nanosecond intervals elapsed since the adoption of the Gregorian calendar in the West, 12:00am Friday October 15, 1582 UTC.

null clj

(null)

Generates the v0 (null) UUID.

squuid clj

(squuid)

Generate a SQUUID (sequential, random) unique identifier.

UUIDable clj protocol

A UUIDable object directly represents a UUID.

as-uuid clj

(as-uuid x)

Coerce the value 'x' to a UUID.

uuidable? clj

(uuidable? x)

Return 'true' if 'x' can be coerced to UUID.

UUIDNameBytes clj protocol

A mechanism intended for user-level extension that defines the decoding rules for the local-part representation of arbitrary Clojure / Java Objects when used for computing namespaced identifiers.

as-byte-array clj

(as-byte-array x)

Extract a byte serialization that represents the 'name' of x, typically unique within a given namespace.

UUIDRfc4122 clj protocol

UUIDRfc9562 clj protocol

A protocol that abstracts an unique identifier as described by IETF RFC9562.
