DescriptorProto

Describes a message type.

EnumDescriptorProto

Describes an enum type.

EnumOptions

EnumValueDescriptorProto

Describes a value within an enum.

EnumValueOptions

ExtensionRangeOptions

FeatureSet

=================================================================== Features

FeatureSetDefaults

A compiled specification for the defaults of a set of features. These messages are generated from FeatureSet extensions and can be used to seed feature resolution. The resolution with this object becomes a simple search for the closest matching edition, followed by proto merges.

FieldDescriptorProto

Describes a field within a message.

FieldOptions

FileDescriptorProto

Describes a complete .proto file.

FileDescriptorSet

The protocol compiler can output a FileDescriptorSet containing the .proto files it parses.

FileOptions

=================================================================== Options

GeneratedCodeInfo

Describes the relationship between generated code and its original source file. A GeneratedCodeInfo message is associated with only one generated source file, but may contain references to different source .proto files.

MessageOptions

MethodDescriptorProto

Describes a method of a service.

MethodOptions

OneofDescriptorProto

Describes a oneof.

OneofOptions

ServiceDescriptorProto

Describes a service.

ServiceOptions

SourceCodeInfo

=================================================================== Optional source code info

UninterpretedOption

A message representing a option the parser does not recognize. This only appears in options protos created by the compiler::Parser class. DescriptorPool resolves these when building Descriptor objects. Therefore, options protos in descriptor objects (e.g. returned by Descriptor::options(), or produced by Descriptor::CopyTo()) will never have UninterpretedOptions in them.

Enums

Edition

The full set of known editions.

SymbolVisibility

Describes the ‘visibility’ of a symbol with respect to the proto import system. Symbols can only be imported when the visibility rules do not prevent it (ex: local symbols cannot be imported). Visibility modifiers can only set on message and enum as they are the only types available to be referenced from other files.
