Variables

var ErrReflectionNotSupported = errors.New("server does not support the reflection API")

ErrReflectionNotSupported is returned by DescriptorSource operations that rely on interacting with the reflection service when the source does not actually expose the reflection service. When this occurs, an alternate source (like file descriptor sets) must be used.

Functions

func GetDescriptorText

func GetDescriptorText(dsc desc.Descriptor, _ DescriptorSource) (string, error)

GetDescriptorText returns a string representation of the given descriptor. This returns a snippet of proto source that describes the given element.

Types

type DescriptorSource

type DescriptorSource interface {
	// ListServices returns a list of fully-qualified service names. It will be all services in a set of
	// descriptor files or the set of all services exposed by a gRPC server.
	ListServices() ([]string, error)
	// FindSymbol returns a descriptor for the given fully-qualified symbol name.
	FindSymbol(fullyQualifiedName string) (desc.Descriptor, error)
	// AllExtensionsForType returns all known extension fields that extend the given message type name.
	AllExtensionsForType(typeName string) ([]*desc.FieldDescriptor, error)
	Files() map[string]*desc.FileDescriptor
}

DescriptorSource is a source of protobuf descriptor information. It can be backed by a FileDescriptorSet proto (like a file generated by protoc) or a remote server that supports the reflection API.

func DescriptorSourceFromFileDescriptorSet

func DescriptorSourceFromFileDescriptorSet(files *descpb.FileDescriptorSet) (DescriptorSource, error)

DescriptorSourceFromFileDescriptorSet creates a DescriptorSource that is backed by the FileDescriptorSet.

func DescriptorSourceFromFileDescriptors

func DescriptorSourceFromFileDescriptors(files ...*desc.FileDescriptor) (DescriptorSource, error)

DescriptorSourceFromFileDescriptors creates a DescriptorSource that is backed by the given file descriptors

func DescriptorSourceFromProtoFiles

func DescriptorSourceFromProtoFiles(importPaths []string, fileNames ...string) (DescriptorSource, error)

DescriptorSourceFromProtoFiles creates a DescriptorSource that is backed by the named files, whose contents are Protocol Buffer source files. The given importPaths are used to locate any imported files.

func DescriptorSourceFromProtoSets

func DescriptorSourceFromProtoSets(fileNames ...string) (DescriptorSource, error)

DescriptorSourceFromProtoSets creates a DescriptorSource that is backed by the named files, whose contents are encoded FileDescriptorSet protos.
