// Creating a new buffer buf := proto.NewBuffer(nil) // Writing a message to the buffer err := buf.EncodeMessage(&myMessage) // Reading a message from the buffer err := buf.DecodeMessage(&myMessage)In these examples, we create a new buffer using the `proto.NewBuffer` function and then use the `EncodeMessage` and `DecodeMessage` methods to write and read Protocol Buffers messages to and from the buffer. This package library is used for serialization and deserialization of Protocol Buffers messages in Go.
