Module protobuf::reflect

Reflection implementation for protobuf data

Generated vs dynamic

rust-protobuf supports reflection for both:

• generated messages (generated rust code)
• dynamic messages (created from arbitrary FileDescriptorProto without code generation)

The API to work with these types of messages is the same.

API

The API roughly follows Google protobuf C++ and Java API. Some minor adjustements are made to make code more idiomatic to rust.

Structs

• EnumDescriptor
  Dynamic representation of enum type.
• EnumValueDescriptor
  Description for enum variant.
• FieldDescriptor
  Field descriptor.
• FileDescriptor
  Reflection for objects defined in .proto file (messages, enums, etc).
• MessageDescriptor
  Dynamic representation of message type.
• MessageRef
  Wrapper around either MessageFull reference or a container for an empty dynamic message.
• MethodDescriptor
  Service method descriptor.
• OneofDescriptor
  Oneof descriptor.
• ReflectEqMode
  Parameter for ReflectEq.
• ReflectMapMut
  Dynamic mutable reference to map field
• ReflectMapRef
  Dynamic reference to map field
• ReflectOptionalRef
  Singular field field and value type.
• ReflectRepeatedMut
  Dynamic mutable reference to repeated field
• ReflectRepeatedRef
  Dynamic reference to repeated field
• ServiceDescriptor
  Dynamic representation of service type.

Enums

• ReflectFieldRef
  Reference to a value stored in a field, optional, repeated or map.
• ReflectValueBox
  Owner value of any elementary type
• ReflectValueRef
  A reference to a value
• RuntimeFieldType
  Reflective representation of field type.
• RuntimeType
  Runtime representation of elementary protobuf type.
• Syntax
  .proto file syntax.

Traits

• ProtobufValue
  Type implemented by all protobuf singular types (primitives, string, messages, enums).
• ReflectEq
  Special version of eq.
