ntypes

Package provides set of types that helps to build complex protobuf messages that contains optional properties. API can be considered as stable.

Types

Basic

• ntypes.Bytes
• ntypes.String
• ntypes.Bool
• ntypes.Int32
• ntypes.Int64
• ntypes.Uint32
• ntypes.Uint64
• ntypes.Float32
• ntypes.Float64

Arrays

• ntypes.BytesArray
• ntypes.StringArray
• ntypes.BoolArray
• ntypes.Int32Array
• ntypes.Int64Array
• ntypes.Uint32Array
• ntypes.Uint64Array
• ntypes.Float32Array
• ntypes.Float64Array

Arrays support is not an SQL standard. Extra import needs to be added to make it working with postgres driver:

import _ "github.com/piotrkowalczuk/ntypes/ntypespq"

Interfaces

Some type implements set of interfaces:

• driver.Valuer excluding Uint64 and some arrays
• proto.Message
• sql.Scanner excluding Uint64 and some arrays
• json.Marshaler
• json.Unmarshaler

Helpers

• ntypes.True
• ntypes.False

Besides that each type implements func <Type>Or(<builtin>) <builtin> {} method. It returns given argument if receiver is not valid or is nil. For example: ntypes.Bool.BoolOr.
