Judy

Judy - playground for learning C and NIFs

This project provides a NIF wrapper around Judy arrays and a chunk of memory, allowing memory efficient storage and fast retrieval of values. The library allocates and manages a large enough chunk of memory to store the values, using the Judy array for finding the proper offset into this chunk. Deletion is currently not supported.

See eunit tests in src/judy.erl for examples.

Usage:

    {ok, J} = judy:new(100, 2).
    ok = judy:insert(J, <<"some key">>, <<123, 123>>).
    <<123, 123>> = judy:get(J, <<"some key">>).
