nulls

README

github.com/gobuffalo/pop/nulls

DEPRECATED: use github.com/gobuffalo/nulls instead.

This package should be used in place of the built-in null types in the sql package.

The real benefit of this packages comes in its implementation of MarshalJSON and UnmarshalJSON to properly encode/decode null values.

Installation

$ go get github.com/gobuffalo/pop/nulls

Supported Datatypes

• string (nulls.String) - Replaces sql.NullString
• int64 (nulls.Int64) - Replaces sql.NullInt64
• float64 (nulls.Float64) - Replaces sql.NullFloat64
• bool (nulls.Bool) - Replaces sql.NullBool
• []byte (nulls.ByteSlice)
• float32 (nulls.Float32)
• int (nulls.Int)
• int32 (nulls.Int32)
• uint32 (nulls.UInt32)
• time.Time (nulls.Time)

Types

type Bool

type Bool = nulls.Bool

Bool replaces sql.NullBool with an implementation that supports proper JSON encoding/decoding.

Deprecated: use github.com/gobuffalo/nulls#Bool instead.

type ByteSlice

type ByteSlice = nulls.ByteSlice

ByteSlice adds an implementation for []byte that supports proper JSON encoding/decoding.

Deprecated: use github.com/gobuffalo/nulls#ByteSlice instead.

type Float32

type Float32 = nulls.Float32

Float32 adds an implementation for float32 that supports proper JSON encoding/decoding.

Deprecated: use github.com/gobuffalo/nulls#Float32 instead.

type Float64

type Float64 = nulls.Float64

Float64 replaces sql.NullFloat64 with an implementation that supports proper JSON encoding/decoding.

Deprecated: use github.com/gobuffalo/nulls#Float64 instead.

type Int

type Int = nulls.Int

Int adds an implementation for int that supports proper JSON encoding/decoding.

Deprecated: use github.com/gobuffalo/nulls#Int instead.

type Int32

type Int32 = nulls.Int32

Int32 adds an implementation for int32 that supports proper JSON encoding/decoding.

Deprecated: use github.com/gobuffalo/nulls#Int32 instead.

type Int64

type Int64 = nulls.Int64

Int64 replaces sql.Int64 with an implementation that supports proper JSON encoding/decoding.

Deprecated: use github.com/gobuffalo/nulls#Int64 instead.

type Nulls

type Nulls struct {
	Value interface{}
}

Nulls a generic nulls type. something that implements nullable interface. can be any of nulls.Int, nulls.uuid.UUID nulls.String, etc.

func New

func New(i interface{}) *Nulls

New returns a wrapper called nulls for the interface passed as a param.

func (*Nulls) Interface

func (nulls *Nulls) Interface() interface{}

Interface calls Interface function for value.

func (*Nulls) Parse

func (nulls *Nulls) Parse(value interface{}) interface{}

Parse parses the specified value to the corresponding nullable type. value is one of the inner value hold by a nullable type. i.e int, string, uuid.UUID etc.

type String

type String = nulls.String

String replaces sql.NullString with an implementation that supports proper JSON encoding/decoding.

Deprecated: use github.com/gobuffalo/nulls#String instead.

type Time

type Time = nulls.Time

Time replaces sql.NullTime with an implementation that supports proper JSON encoding/decoding.

Deprecated: use github.com/gobuffalo/nulls#Time instead.

type UInt32

type UInt32 = nulls.UInt32

UInt32 adds an implementation for int that supports proper JSON encoding/decoding.

Deprecated: use github.com/gobuffalo/nulls#UInt32 instead.

type UUID

type UUID = nulls.UUID

UUID can be used with the standard sql package to represent a UUID value that can be NULL in the database
