This module adds shared support for generic api modules
|
|
|
|
In order to use this module, include it as part of a custom
|
|
module as shown below.
|
|
|
|
** Note: The order of the import statements does matter. **

The 'api' module provides the following common argument specs:
|
|
|
|
* rate limit spec
|
|
- rate: number of requests per time unit (int)
|
|
- rate_limit: time window in which the limit is applied in seconds
|
|
|
|
* retry spec
|
|
- retries: number of attempts
|
|
- retry_pause: delay between attempts in seconds
|
|
