level-option-wrap - wrap `opts.{{g,l}{t,e,te},start,end}` arguments with functions

•    Javascript

With this package you can expose familiar db.createReadStream() options like from leveldb but without leaking information about your internal key representations.For example, suppose you have a list of users using a bytewise keyEncoding and you want to let api consumers constrain the output. If you pass through opts.gt/opts.lt arguments directly, you must communicate to api consumers the internal structure of your keys, which breaks encapsulation.
