Simple library for null values in Go

This library provides simple primitives for nullable variables. Int, Bool, and Float are supported.

	var b null.Bool // This is null

	b.Set(false) // This is false
	b.Set(true) // This is true
	b.Unset() // This is null again.

Types

type Bool 

type Bool struct {
	// contains filtered or unexported fields
}

Bool provides a nullable bool

func NewBool 

func NewBool(value bool) Bool

NewBool returns a fully populated, nullable bool

func (Bool) Get 

func (b Bool) Get() bool

Get returns the actual value of this object

func (Bool) IsNull 

func (b Bool) IsNull() bool

IsNull returns TRUE if this value is null

func (Bool) IsPresent 

func (b Bool) IsPresent() bool

IsPresent returns TRUE if this value is present

func (*Bool) Set 

func (b *Bool) Set(value bool)

Set applies a new value to the nullable item

func (*Bool) Unset 

func (b *Bool) Unset()

Unset removes the value from this item, and sets it to null

type Float 

type Float struct {
	// contains filtered or unexported fields
}

Float provides a nullable float64

func NewFloat 

func NewFloat(value float64) Float

NewFloat returns a fully populated, nullable float64

func (Float) Get 

func (f Float) Get() float64

Get returns the actual value of this object

func (Float) IsNull 

func (f Float) IsNull() bool

IsNull returns TRUE if this value is null

func (Float) IsPresent 

func (f Float) IsPresent() bool

IsPresent returns TRUE if this value is present

func (*Float) Set 

func (f *Float) Set(value float64)

Set applies a new value to the nullable item

func (*Float) Unset 

func (f *Float) Unset()

Unset removes the value from this item, and sets it to null

type Int 

type Int struct {
	// contains filtered or unexported fields
}

Int provides a nullable bool

func NewInt 

func NewInt(value int) Int

NewInt returns a fully populated, nullable bool

func (Int) Get 

func (i Int) Get() int

Get returns the actual value of this object

func (Int) IsNull 

func (i Int) IsNull() bool

IsNull returns TRUE if this value is null

func (Int) IsPresent 

func (i Int) IsPresent() bool

IsPresent returns TRUE if this value is present

func (*Int) Set 

func (i *Int) Set(value int)

Set applies a new value to the nullable item

func (*Int) Unset 

func (i *Int) Unset()

Unset removes the value from this item, and sets it to null
