NullType

Description

This package provides some types representing a type that may be null. NullType implements the sql.Scanner, json.Unmarshaler and json.Marshaler interface for :

  • time.Time
  • string
  • int64
  • int32
  • int16
  • int8
  • uint64
  • uint32
  • uint16
  • uint8
  • bool
  • float64
  • uuid.UUID

NullType and omitempty

By default NullType struct are not empty. To make omitempty tag functional on not valid NullType you have to call EncoderRegister() at the beginning of your program.
