The module function get_next_id starts its id numbering system after the last reserved identifier(RESERVED_LAST). If you wish to use your own identifier generation scheme, identifiers less than or equal to pymousetrap.reserved_ids['RESERVED_LAST'] will cause undesirable results.
|pymousetrap.reserved_ids['TRANSPARENCY']||Used to denote transparency information in a mousetrap.|
|pymousetrap.reserved_ids['PLACEHOLDER']||Used for arbitrary things. Mostly internal, but also a failure value from the instance method lookup_id.|
|pymousetrap.reserved_ids['RESERVED_LAST']||Included to make client code work easily when/if more reserved IDs are added to the system.|
