Functions

func CheckMapDuplicateKey

func CheckMapDuplicateKey(dst, src proto.Message) error

CheckMapDuplicateKey checks the map field's duplicate key in message with the same descriptor.

func EqualMessage

func EqualMessage(v1, v2 pref.Value) bool

EqualMessage reports whether two messages are equal.

func EqualValue

func EqualValue(fd pref.FieldDescriptor, v1, v2 pref.Value) bool

EqualValue compares two singular values. NOTE(wenchy): borrowed from https://github.com/protocolbuffers/protobuf-go/blob/v1.27.1/proto/equal.go#L113

func Merge

func Merge(dst, src proto.Message) error

Merge merges src into dst, which must be a message with the same descriptor.

NOTE: message should only has two kinds of field:

1. list
2. map: src should not has duplicate key in dst

func NewFiles

func NewFiles(protoPaths []string, protoFiles []string, excludeProtoFiles ...string) (*protoregistry.Files, error)

NewFiles creates a new protoregistry.Files from the proto paths and proto Gob filenames.

func ParseFieldValue

func ParseFieldValue(fd pref.FieldDescriptor, rawValue string, locationName string) (v pref.Value, present bool, err error)

func ParseProtos

func ParseProtos(protoPaths []string, protoFiles ...string) (*protoregistry.Files, error)

ParseProtos parses the proto paths and proto files to desc.FileDescriptor slices.

Types

type EnumCache

type EnumCache struct {
	sync.Mutex
	// contains filtered or unexported fields
}

func (*EnumCache) GetValueByAlias

func (ec *EnumCache) GetValueByAlias(ed pref.EnumDescriptor, valueAlias string) (pref.Value, bool)

type TypeInfo

type TypeInfo struct {
	FullName       string
	ParentFilename string
	Kind           types.Kind
}

type TypeInfos

type TypeInfos struct {
	// contains filtered or unexported fields
}

func GetAllTypeInfo

func GetAllTypeInfo(files *protoregistry.Files, protoPackage string) *TypeInfos

func NewTypeInfos

func NewTypeInfos(protoPackage string) *TypeInfos

func (*TypeInfos) Get

func (x *TypeInfos) Get(name string) *TypeInfo

Get retrieves type info by name in proto package. It will auto prepend proto package to inputed name to generate the full name of type.

func (*TypeInfos) GetByFullName

func (x *TypeInfos) GetByFullName(fullName string) *TypeInfo

func (*TypeInfos) Put

func (x *TypeInfos) Put(info *TypeInfo)
