Functions

func IsErrTransient

func IsErrTransient(err error) bool

IsErrTransient returns true if err is t.

func RegisterFiles

func RegisterFiles(fds ...*desc.FileDescriptor) error

Types

type FieldWalker

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

FieldWalker walks fields message fields tree calling func for every field

func NewFieldWalker

func NewFieldWalker() *FieldWalker

func (*FieldWalker) Walk

func (fw *FieldWalker) Walk(md protoreflect.MessageDescriptor, walkFn func(protoreflect.FieldDescriptor))

type GrpcReflectVersion

type GrpcReflectVersion int

const (
	GrpcReflectV1Alpha GrpcReflectVersion = iota
	// automatically determine which grpc reflection version to use
	GrpcReflectAuto
)

func ParseGrpcReflectVersion

func ParseGrpcReflectVersion(s string) GrpcReflectVersion

type MsgFormat

type MsgFormat int

Proto message format

const (
	JSON MsgFormat = iota
	Text
)

func ParseMsgFormat

func ParseMsgFormat(s string) MsgFormat

func (MsgFormat) String

func (f MsgFormat) String() string

type ServiceCaller

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

func NewServiceCaller

func NewServiceCaller(connFact *rpc.GrpcConnFactory, inMsgFormat, outMsgFormat MsgFormat, outJsonNames bool) *ServiceCaller

func (*ServiceCaller) CallClientStream

func (sc *ServiceCaller) CallClientStream(ctx context.Context, serviceTarget string, methodDesc *desc.MethodDescriptor, messages [][]byte, callOpts ...grpc.CallOption) ([]byte, error)

CallClientStream allows calling unary or client stream methods as they both return only a single result

func (*ServiceCaller) CallStream

func (sc *ServiceCaller) CallStream(ctx context.Context, serviceTarget string, methodDesc *desc.MethodDescriptor, messages [][]byte, callOpts ...grpc.CallOption) (chan []byte, chan error)

type ServiceMeta

type ServiceMeta struct {
	Name    string
	Methods []*desc.MethodDescriptor
	File    *desc.FileDescriptor
}

type ServiceMetaData

type ServiceMetaData interface {
	GetServiceMetaDataList(context.Context) (ServiceMetaList, error)
	GetAdditionalFiles() ([]*desc.FileDescriptor, error)
}

func NewServiceMetaData

func NewServiceMetaData(cfg *ServiceMetaDataConfig) ServiceMetaData

NewServiceMetaData returns new instance of ServiceMetaData that reads service metadata by calling grpc Reflection service of the target

func NewServiceMetadataProto

func NewServiceMetadataProto(protoPath, protoImports []string) ServiceMetaData

NewServiceMetadataProto returns new instance of ServiceMetaData that reads service metadata from proto files on disk. protoPath - proto files or directories of proto files protoImports - additional directories to search for proto files dependencies

type ServiceMetaDataConfig

type ServiceMetaDataConfig struct {
	ConnFact       *rpc.GrpcConnFactory
	Target         string
	ProtoImports   []string
	Deadline       int
	ReflectVersion GrpcReflectVersion
}

type ServiceMetaList

type ServiceMetaList []*ServiceMeta

func (ServiceMetaList) Files

func (l ServiceMetaList) Files() []*desc.FileDescriptor
