IsTypePackable()

def google.protobuf.internal.wire_format.IsTypePackable

(

field_type

)

Return true iff packable = true is valid for fields of this type.

Args:
  field_type: a FieldDescriptor::Type value.

Returns:
  True iff fields of this type are packable.

def google.protobuf.internal.wire_format.PackTag	(		field_number,
			wire_type
	)

Returns an unsigned 32-bit integer that encodes the field number and
wire type information in standard protocol message wire format.

Args:
  field_number: Expected to be an integer in the range [1, 1 << 29)
  wire_type: One of the WIRETYPE_* constants.
