A limiter for the attached buckets.
Distributes tokens fairly between buckets, with overflow distributed so that the total limit is not exceeded.
Limiters can either be added to rate_limit_manager, or as sub-limiter to another limiter. For leaf buckets, the actual rate limit is the lowest limit imposed by any of its parents.
| void add | ( | bucket_base * | bucket | ) |
Adds a bucket to the limiter.
Child buckets get removed automatically when they are destroyed, or manually when the child's remove_bucket is called.
| void set_limits | ( | rate::type | download_limit, |
| rate::type | upload_limit | ||
| ) |
Sets the number of octets all buckets combined may consume each second.
Pass rate::unlimited if there should be no limit.
The default limit is rate::unlimited.
