ulid

Overview ¶

Package ulid generates ULIDs (Universally Unique Lexicographically Sortable IDs) with zero external dependencies. A ULID is a 128-bit value: a 48-bit millisecond timestamp followed by 80 bits of randomness, encoded as 26 Crockford base32 characters. Lexical order matches creation order, which is exactly the "sortable by creation time" property nt relies on (SPEC §4).
