None of these methods have been in a past released version so I don't think we should worry about backwards compatibility.
Changes as follows:
- Renamed ``compression`` to ``set_compression_type``. I think this is a much clearer name
- Renamed ``add_merge_operator`` to ``set_merge_operator`` and ``add_comparator`` to ``set_comparator``. Both of these methods replace the entire value of their respective option so "add" is the wrong term to use here.
- Renamed ``set_block_cache_size_mb`` to ``rocksdb_options_optimize_for_point_lookup``. To match RocksDB's API
This makes it easier for people who are using the try!() macro to convert errors into their own Error type. It isn't possible to diffrentiate between errors raised from RocksDB and other string errors at the moment.
This adds a simple ``Error`` type that wraps ``String``. People using RocksDB can now implement ``impl From<rocksdb::Error> for MyError`` and add custom behaviour for handling RocksDB errors.
