Module Contents¶

Note

We take out the following 9 chars (leaving 27), because there is visual ambiguity: 0/O/D, 1/I, 8/B, 2/Z.

MAX_OID = 9007199254740992[source]¶

Valid OID are from the integer range [0, MAX_OID].

The upper bound 2**53 is chosen since it is the maximum integer that can be represented as a IEEE double such that all smaller integers are representable as well.

Hence, IDs can be safely used with languages that use IEEE double as their main (or only) number type (JavaScript, Lua, etc).
