How do I create a pool of reusable buffers in Go?

In Go, managing memory effectively is essential for performance. One effective way to do this is by using a pool of reusable buffers. The `sync.Pool` type provides a simple and efficient way to store and reuse temporary objects.

Here's an example of how to create a pool of bytes buffers:


        package main

        import (
            "bytes"
            "fmt"
            "sync"
        )

        func main() {
            var bufferPool = sync.Pool{
                New: func() interface{} {
                    return new(bytes.Buffer)
                },
            }

            // Example of using the buffer pool
            buffer := bufferPool.Get().(*bytes.Buffer)
            defer bufferPool.Put(buffer)

            buffer.WriteString("Hello, ")
            buffer.WriteString("World!")

            fmt.Println(buffer.String()) // Output: Hello, World!

            // Reset buffer for reuse
            buffer.Reset()
            buffer.WriteString("Another use of the buffer.")
            fmt.Println(buffer.String()) // Output: Another use of the buffer.
        }
