mtbl_source - obtain key-value entries from a data source

       The mtbl_source interface provides an abstraction for reading key-value entries from mtbl data sources.

       mtbl_source_iter() provides an iterator over all of the entries in the data source.

       mtbl_source_get() provides an exact match iterator which returns all entries whose key matches the key
       provided in the arguments key and len_key.

       mtbl_source_get_prefix() provides a prefix iterator which returns all entries whose keys start with
       prefix and are at least len_prefix bytes long.

       mtbl_source_get_range() provides a range iterator which returns all entries whose keys are between key0
       and key1 inclusive.

       mtbl_source_write() is a convenience function for reading all of the entries from a source and writing
       them to an mtbl_writer object. It is equivalent to calling mtbl_writer_add() on all of the entries
       returned from mtbl_source_iter().

mtbl_source_iter(), mtbl_source_get(), mtbl_source_get_prefix(), and mtbl_source_get_range() return
       mtbl_iter objects.

       mtbl_source_write() returns mtbl_res_success if all of the entries in the data source were successfully
       written to the mtbl_writer argument, and mtbl_res_failure otherwise.
