** Overview
[[http://travis-ci.org/basho/ebloom][Travis-CI]] :: [[https://secure.travis-ci.org/basho/ebloom.png]]

=ebloom= is a NIF wrapper around a basic bloom filter.

** Quick Start
   You must have [[http://erlang.org/download.html][Erlang/OTP R13B04]] or later and a GNU-style build
   system to compile and run =ebloom=.

#+BEGIN_SRC shell
git clone git://github.com/basho/ebloom.git
cd ebloom
make
#+END_SRC

   Start up an Erlang shell with the path to =ebloom= included.

#+BEGIN_SRC shell
erl -pa path/to/ebloom/ebin
#+END_SRC

   Create a new bloom filter, insert elements, and test for an
   elements presence.

#+BEGIN_SRC erlang
1> PredictedElementCount=5.
5
2> FalsePositiveProbability=0.01.

3> RandomSeed=123.
123
4> {ok, Ref} = ebloom:new(PredictedElementCount, FalsePositiveProbability, RandomSeed).
{ok,<<>>}
5> ebloom:insert(Ref, <<"abcdef">>).
ok
6> true = ebloom:contains(Ref, <<"abcdef">>).
true
7> false = ebloom:contains(Ref, <<"zzzzzz">>).
false
#+END_SRC
