type CheckInitializedInput

type CheckInitializedInput = struct {

	Message protoreflect.Message

CheckInitializedInput is input to the CheckInitialized method.

type CheckInitializedOutput

type CheckInitializedOutput = struct {

CheckInitializedOutput is output from the CheckInitialized method.

type ExtensionRangeV1

type ExtensionRangeV1 struct {
	Start, End int32 // both inclusive

type MarshalInput

type MarshalInput = struct {

	Message protoreflect.Message
	Buf     []byte // output is appended to this buffer
	Flags   MarshalInputFlags

MarshalInput is input to the Marshal method.

type MarshalInputFlags

type MarshalInputFlags = uint8

MarshalInputFlags configure the marshaler. Most flags correspond to fields in proto.MarshalOptions.

const (
	MarshalDeterministic MarshalInputFlags = 1 << iota

type MarshalOutput

type MarshalOutput = struct {

	Buf []byte // contains marshaled message

MarshalOutput is output from the Marshal method.

type MergeInput

type MergeInput = struct {

	Source      protoreflect.Message
	Destination protoreflect.Message

MergeInput is input to the Merge method.

type MergeOutput

type MergeOutput = struct {

	Flags MergeOutputFlags

MergeOutput is output from the Merge method.

type MergeOutputFlags

type MergeOutputFlags = uint8

MergeOutputFlags are output from the Merge method.

const (
	// MergeComplete reports whether the merge was performed.
	// If unset, the merger must have made no changes to the destination.
	MergeComplete MergeOutputFlags = 1 << iota

type MessageV1

type MessageV1 interface {
	String() string

type Methods

type Methods = struct {

	// Flags indicate support for optional features.
	Flags SupportFlags

	// Size returns the size in bytes of the wire-format encoding of a message.
	// Marshal must be provided if a custom Size is provided.
	Size func(SizeInput) SizeOutput

	// Marshal formats a message in the wire-format encoding to the provided buffer.
	// Size should be provided if a custom Marshal is provided.
	// It must not return an error for a partial message.
	Marshal func(MarshalInput) (MarshalOutput, error)

	// Unmarshal parses the wire-format encoding and merges the result into a message.
	// It must not reset the target message or return an error for a partial message.
	Unmarshal func(UnmarshalInput) (UnmarshalOutput, error)

	// Merge merges the contents of a source message into a destination message.
	Merge func(MergeInput) MergeOutput

	// CheckInitialized returns an error if any required fields in the message are not set.
	CheckInitialized func(CheckInitializedInput) (CheckInitializedOutput, error)

Methods is a set of optional fast-path implementations of various operations.

type SizeInput

type SizeInput = struct {

	Message protoreflect.Message
	Flags   MarshalInputFlags

SizeInput is input to the Size method.

type SizeOutput

type SizeOutput = struct {

	Size int

SizeOutput is output from the Size method.

type SupportFlags

type SupportFlags = uint64

SupportFlags indicate support for optional features.

const (
	// SupportMarshalDeterministic reports whether MarshalOptions.Deterministic is supported.
	SupportMarshalDeterministic SupportFlags = 1 << iota

	// SupportUnmarshalDiscardUnknown reports whether UnmarshalOptions.DiscardUnknown is supported.

type UnmarshalInput

type UnmarshalInput = struct {

	Message  protoreflect.Message
	Buf      []byte // input buffer
	Flags    UnmarshalInputFlags
	Resolver interface {
		FindExtensionByName(field protoreflect.FullName) (protoreflect.ExtensionType, error)
		FindExtensionByNumber(message protoreflect.FullName, field protoreflect.FieldNumber) (protoreflect.ExtensionType, error)

UnmarshalInput is input to the Unmarshal method.

type UnmarshalInputFlags

type UnmarshalInputFlags = uint8

UnmarshalInputFlags configure the unmarshaler. Most flags correspond to fields in proto.UnmarshalOptions.

const (
	UnmarshalDiscardUnknown UnmarshalInputFlags = 1 << iota

type UnmarshalOutput

type UnmarshalOutput = struct {

	Flags UnmarshalOutputFlags

UnmarshalOutput is output from the Unmarshal method.

type UnmarshalOutputFlags

type UnmarshalOutputFlags = uint8

UnmarshalOutputFlags are output from the Unmarshal method.

const (
	// UnmarshalInitialized may be set on return if all required fields are known to be set.
	// If unset, then it does not necessarily indicate that the message is uninitialized,
	// only that its status could not be confirmed.
	UnmarshalInitialized UnmarshalOutputFlags = 1 << iota
