Safe and Fast Bloom Filter for Erlang

Without docker you must install erlang >=20.1 and rust >=1.23 on your machine. After you can run these goals:

release: rebar3 as prod release

test: rebar3 as test ct

In Docker enviroment:

• make build_imgs - build docker images
• make up - run sandbox
• make down - terminate sandbox
• make tests - run tests
• make lint - linter
• make xref - xref analysis
• make prod - generate release for target

Using as a lib

1. Add deps in rebar.conf:

{deps, [
    {erbloom, ".*", {git, "https://github.com/Vonmo/erbloom.git", {tag, "v2.0.0"}}}      
]}

2. Now you can create a new filter instance: {ok, Filter} = bloom:new(9585059,1000000).
3. Set a new element bloom:set(Filter, "somekey").
4. Check up element bloom:check(Filter, "anotherkey").
5. Serialize {ok,{Bitmap,NumBits,NumFuns,{Sv00,Sv01},{Sv10,Sv11}}} = bloom:serialize(Filter).
6. Deserialize bloom:deserialize(Bitmap,NumBits,NumFuns,Sv00,Sv01,Sv10,Sv11).
