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 added in v0.7.0

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) Defined

func (k Key) Defined() bool

Defined returns true for non-empty keys.

func (Key) Float32

func (k Key) Float32(v float32) KeyValue

Float32 creates a KeyValue instance with a FLOAT32 Value.

If creating both key and a float32 value at the same time, then instead of calling kv.Key(name).Float32(value) consider using a convenience function provided by the api/key package - key.Float32(name, value).

func (Key) Float64

func (k Key) Float64(v float64) KeyValue

Float64 creates a KeyValue instance with a FLOAT64 Value.

If creating both key and a float64 value at the same time, then instead of calling kv.Key(name).Float64(value) consider using a convenience function provided by the api/key package - key.Float64(name, value).

func (Key) Int

func (k Key) Int(v int) KeyValue

Int creates a KeyValue instance with either an INT32 or an INT64 Value, depending on whether the int type is 32 or 64 bits wide.

func (Key) Int32

func (k Key) Int32(v int32) KeyValue

Int32 creates a KeyValue instance with an INT32 Value.

func (Key) Int64

func (k Key) Int64(v int64) KeyValue

Int64 creates a KeyValue instance with an INT64 Value.

func (Key) String

func (k Key) String(v string) KeyValue

String creates a KeyValue instance with a STRING Value.

If creating both key and a string 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.String(name, value).

func (Key) Uint

func (k Key) Uint(v uint) KeyValue

func (Key) Uint32

func (k Key) Uint32(v uint32) KeyValue

Uint32 creates a KeyValue instance with a UINT32 Value.

If creating both key and a uint32 value at the same time, then instead of calling kv.Key(name).Uint32(value) consider using a convenience function provided by the api/key package - key.Uint32(name, value).

func (Key) Uint64

func (k Key) Uint64(v uint64) KeyValue

	INT64               // 64 bit signed integral value, use AsInt64() to get it.
	UINT32              // 32 bit unsigned integral value, use AsUint32() to get it.
