import "gopkg.in/guregu/null.v4"

null is a library with reasonable options for dealing with nullable SQL and JSON values

There are two packages: null and its subpackage zero.

Types in null will only be considered null on null input, and will JSON encode to null. If you need zero and null be considered separate values, use these.

Types in zero are treated like zero values in Go: blank string input will produce a null zero.String, and null Strings will JSON encode to "". Zero values of these types will be considered null to SQL. If you need zero and null treated the same, use these.

All types implement sql.Scanner and driver.Valuer, so you can use this library in place of sql.NullXXX. All types also implement: encoding.TextMarshaler, encoding.TextUnmarshaler, json.Marshaler, and json.Unmarshaler. A null object's MarshalText will return a blank string.

null package

import "gopkg.in/guregu/null.v4"

null.String

Nullable string.

Marshals to JSON null if SQL source data is null. Zero (blank) input will not produce a null String.

null.Int

Nullable int64.

Marshals to JSON null if SQL source data is null. Zero input will not produce a null Int.

null.Float

Nullable float64.

Marshals to JSON null if SQL source data is null. Zero input will not produce a null Float.

null.Bool

Nullable bool.

Marshals to JSON null if SQL source data is null. False input will not produce a null Bool.

null.Time

Marshals to JSON null if SQL source data is null. Zero input will not produce a null Time.

zero package

import "gopkg.in/guregu/null.v4/zero"

zero.String

Nullable string.

Will marshal to a blank string if null. Blank string input produces a null String. Null values and zero values are considered equivalent.

zero.Int

Nullable int64.

Will marshal to 0 if null. 0 produces a null Int. Null values and zero values are considered equivalent.

zero.Float

Nullable float64.

Will marshal to 0.0 if null. 0.0 produces a null Float. Null values and zero values are considered equivalent.

zero.Bool

Nullable bool.

Will marshal to false if null. false produces a null Float. Null values and zero values are considered equivalent.

zero.Time

Will marshal to the zero time if null. Uses time.Time's marshaler.

Can you add support for other types?

This package is intentionally limited in scope. It will only support the types that driver.Value supports. Feel free to fork this and add more types if you want.

Can you add a feature that ____?

This package isn't intended to be a catch-all data-wrangling package. It is essentially finished. If you have an idea for a new feature, feel free to open an issue to talk about it or fork this package, but don't expect this to do everything.

Package history

As of v4, unmarshaling from JSON sql.NullXXX JSON objects (ex. {"Int64": 123, "Valid": true}) is no longer supported. It's unlikely many people used this, but if you need it, use v3.

Bugs

json's ",omitempty" struct tag does not work correctly right now. It will never omit a null or empty String. This might be fixed eventually.

Overview

Package null contains SQL types that consider zero input and null input as separate values, with convenient support for JSON and text marshaling. Types in this package will always encode to their null value if null. Use the zero subpackage if you want zero values and null to be treated the same.

IsZero returns true for invalid Times, hopefully for future omitempty support. A non-null Time with a zero value will not be considered zero.

func (TimeSkipErr) MarshalJSON added in v1.0.18 

func (t TimeSkipErr) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler. It will encode null if this time is null.

func (TimeSkipErr) MarshalText added in v1.0.18 

func (t TimeSkipErr) MarshalText() ([]byte, error)

MarshalText implements encoding.TextMarshaler. It returns an empty string if invalid, otherwise time.Time's MarshalText.

func (TimeSkipErr) Ptr added in v1.0.18 

func (t TimeSkipErr) Ptr() *time.Time

Ptr returns a pointer to this Time's value, or a nil pointer if this Time is null.

func (*TimeSkipErr) Set added in v1.0.18 

func (t *TimeSkipErr) Set(v time.Time)

Set changes this Time's value and sets it to be non-null.

func (*TimeSkipErr) UnmarshalJSON added in v1.0.18 

func (t *TimeSkipErr) UnmarshalJSON(data []byte) error

UnmarshalJSON implements json.Unmarshaler. It supports string and null input.

func (*TimeSkipErr) UnmarshalText added in v1.0.18 

func (t *TimeSkipErr) UnmarshalText(text []byte) error

UnmarshalText implements encoding.TextUnmarshaler. It has backwards compatibility with v3 in that the string "null" is considered equivalent to an empty string and unmarshaling will succeed. This may be removed in a future version.

func (TimeSkipErr) Value added in v1.0.18 

func (t TimeSkipErr) Value() (driver.Value, error)

Value implements the driver Valuer interface.

func (TimeSkipErr) ValueOrZero added in v1.0.18 

func (t TimeSkipErr) ValueOrZero() time.Time

ValueOrZero returns the inner value if valid, otherwise zero.
