Namespaces
namespace	operations_research
	In SWIG mode, we don't want anything besides these top-level includes.
namespace	operations_research::internal
	End of the interface. Below is the implementation.

Enumerations
enum class	operations_research::ProtoWriteFormat { operations_research::kProtoText , operations_research::kProtoBinary , operations_research::kJson , operations_research::kCanonicalJson }

Functions
absl::StatusOr< std::string >	operations_research::ReadFileToString (absl::string_view filename)
	Reads a file, optionally gzipped, to a string.
absl::Status	operations_research::ReadFileToProto (absl::string_view filename, google::protobuf::Message *proto, bool allow_partial)
absl::Status	operations_research::StringToProto (absl::string_view data, google::protobuf::Message *proto, bool allow_partial=false)
	Exactly like ReadFileToProto(), but directly from the contents.
