Package ring provides a high performance and thread safe Go implementation of a bloom filter.
Please see the godoc for usage.
Running make will perform unit tests, comparing the target false positive rate
with the actual rate. Here is a test against 1 million elements with a targeted
false positive rate of 0.1%. Tests fail if the number of false positives exceeds
the target.
