- leveldb-iterator db #!key (finalizer ...) (seek #f) (verify-checksums #t) (fill-cache #t)procedure
Create a leveldb-iterator-t instance which you can use to seek, and read keys and values from db. It is very efficient at moving through keys sequentially using leveldb-iter-next.
seek, if present and not #f, will be passed to a call to leveldb-iter-seek. As with leveldb-iter-seek, you can specify 'first to initialize the iterator to the first entry, for example.
