The `github.com/calmh/syncthing/xdr` library in Go provides a writer that can encode data in the XDR format. XDR stands for External Data Representation, and is commonly used for efficient data exchange over different system architectures.

Using the `Writer` provided by this package, developers can easily encode data into XDR format and send it over the network or write it to a filesystem. Here are some examples of how to use the `Writer`:

package main

import (
    "bytes"
    "github.com/calmh/syncthing/xdr"
)

func main() {
    // Creating a new bytes.Buffer to write the encoded data.
    buf := new(bytes.Buffer)

    // Create a new xdr.Writer to write to the buffer.
    w := xdr.NewWriter(buf)

    // Encode a string
    w.WriteString("Hello, world!")

    // Encode an array of integers
    w.WriteInt32Array([]int32{1, 2, 3, 4, 5})

    // Encode a struct
    type person struct {
        Name string
        Age  int
    }
    p := person{Name: "Alice", Age: 30}
    w.WriteStruct(&p)

    // Flush the writer and print the encoded data.
    w.Flush()
    println(buf.Bytes())
}

In this example, we create a new `bytes.Buffer` to write the encoded data to. We then create a new `xdr.Writer` and use it to encode a string, an array of integers, and a struct. Finally, we flush the writer and print the contents of the buffer. This package is used in the Syncthing project to encode data for communication between peers over the network.
