Universally unique lexicographically sortable identifier (Python library)
A ULID is a Universally Unique Lexicographically sortable Identifier. It is:
* 128-bit compatible with ``UUID`` * 1.21e+24 unique ULIDs per millisecond * Lexicographically sortable! * Canonically encoded as a 26 character string, as opposed to the 36 character UUID * Uses Crockford's base32 for better efficiency and readability (5 bits per character) * Case insensitive * No special characters (URL safe)
