A FieldDescriptor instance has the following attributes:
name: (str) Name of this field, exactly as it appears in .proto.
full_name: (str) Name of this field, including containing scope. This is
particularly relevant for extensions.
camelcase_name: (str) Camelcase name of this field.
index: (int) Dense, 0-indexed index giving the order that this
field textually appears within its message in the .proto file.
number: (int) Tag number declared for this field in the .proto file.
type: (One of the TYPE_* constants below) Declared type.
cpp_type: (One of the CPPTYPE_* constants below) C++ type used to
represent this field.
label: (One of the LABEL_* constants below) Tells whether this
field is optional, required, or repeated.
has_default_value: (bool) True if this field has a default value defined,
otherwise false.
default_value: (Varies) Default value of this field. Only
meaningful for non-repeated scalar fields. Repeated fields
should always set this to [], and non-repeated composite
fields should always set this to None.
containing_type: (Descriptor) Descriptor of the protocol message
type that contains this field. Set by the Descriptor constructor
if we're passed into one.
Somewhat confusingly, for extension fields, this is the
descriptor of the EXTENDED message, not the descriptor
of the message containing this field. (See is_extension and
extension_scope below).
message_type: (Descriptor) If a composite field, a descriptor
of the message type contained in this field. Otherwise, this is None.
enum_type: (EnumDescriptor) If this field contains an enum, a
descriptor of that enum. Otherwise, this is None.
is_extension: True iff this describes an extension field.
extension_scope: (Descriptor) Only meaningful if is_extension is True.
Gives the message that immediately contains this extension field.
Will be None iff we're a top-level (file-level) extension field.
options: (descriptor_pb2.FieldOptions) Protocol message field options or
None to use default field options.
containing_oneof: (OneofDescriptor) If the field is a member of a oneof
union, contains its descriptor. Otherwise, None.
file: (FileDescriptor) Reference to file descriptor.

t+|��S(sMake a protobuf Descriptor given a DescriptorProto protobuf.
Handles nested descriptors. Note that this is limited to the scope of defining
a message inside of another message. Composite fields can currently only be
resolved if the message is defined in the same scope as the field.
Args:
desc_proto: The descriptor_pb2.DescriptorProto protobuf message.
package: Optional package name for the new message Descriptor (string).
build_file_if_cpp: Update the C++ descriptor pool if api matches.
Set to False on recursion, so no duplicates are created.
syntax: The syntax/semantics that should be used. Set to "proto3" to get
proto3 field presence semantics.
Returns:
A Descriptor for protobuf messages.
