null 🚫
Simple library for null values in Go
This library provides simple, idiomatic primitives for nullable values in Go. It supports Int, Bool, and Float types.
// "b" is null, and ready to use
var b null.Bool
// Set value to false
b.Set(false)
// Set value to true
b.Set(true)
// Get the value
b.Bool()
// Make the value null again
b.Unset()

Types ¶
type Bool ¶
type Bool struct {
// contains filtered or unexported fields
}
Bool provides a nullable bool
func (Bool) Interface ¶ added in v0.4.1
func (b Bool) Interface() interface{}
Interface returns the boolean value (if present) or NIL
func (Bool) MarshalJSON ¶ added in v0.4.0
MarshalJSON implements the json.Marshaller interface
func (*Bool) UnmarshalJSON ¶ added in v0.4.0
UnmarshalJSON implements the json.Unmarshaller interface
type Float ¶
type Float struct {
// contains filtered or unexported fields
}
Float provides a nullable float64
func (Float) Interface ¶ added in v0.4.1
func (f Float) Interface() interface{}
Interface returns the float64 value (if present) or NIL
func (Float) MarshalJSON ¶ added in v0.4.0
MarshalJSON implements the json.Marshaller interface
func (*Float) UnmarshalJSON ¶ added in v0.4.0
UnmarshalJSON implements the json.Unmarshaller interface
type Int ¶
type Int struct {
// contains filtered or unexported fields
}
Int provides a nullable bool
func (Int) Interface ¶ added in v0.4.1
func (i Int) Interface() interface{}
Interface returns the int value (if present) or NIL
func (Int) MarshalJSON ¶ added in v0.4.0
MarshalJSON implements the json.Marshaller interface
func (*Int) UnmarshalJSON ¶ added in v0.4.0
UnmarshalJSON implements the json.Unmarshaller interface
