there is no support for the generation of 'v1' style UUIDs in.

this library provides a complete set of comparison operators for.

this library's UUID representation is more compact.

The UUID provided by this library is comparable to the one provided by

Function uuid-timestamp object → variant.

Function uuid-clock-sequence object → variant.

Provided for completeness, but I have yet to find a reason for using any Certain extractor functions (like uuid-clock-sequence, uuid-timestamp, etc.)Īre meaningful only for certain variants, if at all. The following functions extract information about variant and version of a Only one of generator or random-state can beįunction uuid-for-name string &key start end digest namespace → object If neither is given, the function uses random with the value of *random-state* Must be a function of a single argument, a positive integer N, which returnsĪn (array (unsigned-byte) (N)) of N random bytes.

The ordering predicates can be used with data structures like FSetįunction uuid/= object1 object2 → booleanĮach of these functions compares the argument values, both of which mustīe instances of type uuid, and returns true, if the values have the (but (make-hash-table :test #'uuid= :hash-function #'uuid-hash) In SBCL you can (sb-ext:define-hash-table-test uuid= #'uuid-hash)Īnd then use this as (make-hash-table :test 'uuid=) The hash function can be used in Common Lisp implementations, whichįor example, in CCL (make-hash-table :test 'uuid= :hash-function 'uuid-hash)

Implementation of the predicates is more efficient than that.

Ordering of the string representations of UUIDs, i.e., it is always the The ordering carefully reflects the lexicographic Ordering on UUIDs is total, i.e., every two UUID instances v1 and v2 Values of type UUID can be compared for equality as well as order. Tests, whether object is a value of type uuid. Basically, a 128 bit number (more or less) Uses the Leach-Salz variant of UUIDs, but can represent all kinds of UUIDs. This is a simple library to work with UUID values.
