Types

type Key 

type Key string

Key represents the key part in key-value pairs. It's a string. The allowed character set in the key depends on the use of the key.

func (Key) Array 

func (k Key) Array(v interface{}) KeyValue

Array creates a KeyValue instance with a ARRAY Value.

If creating both key and a array value at the same time, then instead of calling kv.Key(name).String(value) consider using a convenience function provided by the api/key package - key.Array(name, value).

func (Key) Bool 

func (k Key) Bool(v bool) KeyValue

Bool creates a KeyValue instance with a BOOL Value.

If creating both key and a bool value at the same time, then instead of calling kv.Key(name).Bool(value) consider using a convenience function provided by the api/key package - key.Bool(name, value).

func (Key) Float64 

func (k Key) Float64(v float64) KeyValue
