import ( "git.apache.org/thrift.git/lib/go/thrift" "io/ioutil" ) func writeDataToFile(data MyStruct, filePath string) error { // create a binary output protocol transport := thrift.NewTMemoryBuffer() protocol := thrift.NewTBinaryProtocol(transport) // write data to the protocol err := data.Write(protocol) if err != nil { return err } // write protocol data to file fileData, err := ioutil.ReadAll(transport) if err != nil { return err } err = ioutil.WriteFile(filePath, fileData, 0644) if err != nil { return err } return nil }In the above example, a `MyStruct` is written to a file in binary format using the Thrift protocol. The `thrift.NewTBinaryProtocol` function is used to create a new binary protocol, and the `data.Write` method is used to write the data to the protocol. The protocol data is then read using `ioutil.ReadAll`, and written to a file using `ioutil.WriteFile`. Overall, the go git.apache.org.thrift.git.lib.go.thrift TProtocol WriteBinary package library provides a convenient and efficient way to serialize and deserialize data using the Thrift protocol in a binary format.
