import ( "github.com/tinylib/msgp/msgp" "bytes" ) type Person struct { Name string Age int } func main() { person := Person{Name: "Alice", Age: 25} // Initialize a buffer to hold the MessagePack-encoded data buf := &bytes.Buffer{} // Create a new msgp Writer that writes to the buffer writer := msgp.NewWriter(buf) // Use the writer to write the Person struct to the buffer writer.WriteMapHeader(2) writer.WriteString("Name") writer.WriteString(person.Name) writer.WriteString("Age") writer.WriteInt(int64(person.Age)) // Cleanly close the writer writer.Flush() }In this example, we define a simple struct `Person` with a `Name` and an `Age` field. We create a new buffer to hold the MessagePack-encoded data, and then initialize a new msgp Writer to write to that buffer. We use the writer to write the `Person` struct to the buffer, encoding the `Name` field as a string and the `Age` field as an integer. Finally, we flush the writer to ensure any remaining data is properly written to the buffer. Overall, the github.com.tinylib.msgp.msgp Writer package is a useful tool for working with MessagePack in Go, allowing you to easily serialize Go structures into the compact and efficient MessagePack format.
