uid

A package for generating unique identifiers, loosely based on MongoDB's ObjectId.

Identifiers are 12-bytes and roughly time sortable.

• a 4-byte value representing the seconds since the Unix epoch,
• a 3-byte machine identifier,
• a 2-byte process id, and
• a 3-byte counter, starting with a random value.
