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.


times, endians


Oid = object
  time: int32                  ## 
  fuzz: int32                  ## 
  count: int32                 ##
an OID


proc `==`(oid1: Oid; oid2: Oid): bool {.raises: [], tags: [].}
Compare two Mongo Object IDs for equality
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.
