Module oids

Nim OID support. An OID is a global ID that consists of a timestamp, a unique counter and a random value. This combination should suffice to produce a globally distributed unique ID. This implementation was extracted from the Mongodb interface and it thus binary compatible with a Mongo OID.

This implementation calls math.randomize() for the first call of genOid.

proc hexbyte(hex: char): int {...}{.raises: [], tags: [].}

proc parseOid(str: cstring): Oid {...}{.raises: [], tags: [].}

parses an OID.

proc oidToString(oid: Oid; str: cstring) {...}{.raises: [], tags: [].}

proc `$`(oid: Oid): string {...}{.raises: [], tags: [].}

proc genOid(): Oid {...}{.raises: [], tags: [].}

generates a new OID.

proc generatedTime(oid: Oid): Time {...}{.raises: [], tags: [].}

returns the generated timestamp of the OID.
