Package defval marshals and unmarshals textual forms of default values.

    This package handles both the form historically used in Go struct field tags and also the form used by google.protobuf.FieldDescriptorProto.default_value since they differ in superficial ways.

    func Marshal

    func Marshal(v pref.Value, ev pref.EnumValueDescriptor, k pref.Kind, f Format) (string, error)

      Marshal serializes v as the default string according to the given kind k. When specifying the Descriptor format for an enum kind, the associated enum value descriptor must be provided.

      func Unmarshal

        Unmarshal deserializes the default string s according to the given kind k. When k is an enum, a list of enum value descriptors must be provided.


        type Format

        type Format int

          Format is the serialization format used to represent the default value.

          const (
          	// Descriptor uses the serialization format that protoc uses with the
          	// google.protobuf.FieldDescriptorProto.default_value field.
          	Descriptor Format
          	// GoTag uses the historical serialization format in Go struct field tags.
