package defval

import "google.golang.org/protobuf/internal/encoding/defval"

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.

Functions ¶

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 ¶

func Unmarshal(s string, k pref.Kind, evs pref.EnumValueDescriptors, f Format) (pref.Value, pref.EnumValueDescriptor, error)

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.

Types ¶

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.
	GoTag
)
