can support `incr` 、`decr` and `keys` about gokv

[GwynethLlewelyn]

Hello,

Is this a question?

As far as I know, gokv supports Get(), Set() and Delete() (and Close() at the end).

See https://github.com/philippgille/gokv/#simple-interface:

type Store interface {
    Set(k string, v interface{}) error
    Get(k string, v interface{}) (found bool, err error)
    Delete(k string) error
    Close() error
}

where v is basically whatever structure/type you wish.

Everything else it's up to you to write! You can use int for v, and write an incr(k string) function that gets the value for a key, increments it, and sets it again with the new value (and similarly for decr(k string)). I'm not sure what you mean with keys — a list of keys that store a specific value? Well, again, you'll have to do all that by yourself...
