How do I work with byte buffers efficiently in Go?

Working with Byte Buffers Efficiently in Go

In Go, the bytes.Buffer type provides a powerful way to work with byte buffers. It is safe for concurrent use and helps avoid unnecessary copies during operations. Here are a few methods to efficiently manage byte buffers:

  • Write: Write bytes to the buffer.
  • Read: Read bytes from the buffer.
  • String: Convert the buffer to a string.
  • Reset: Clear the buffer without allocating new memory.

Example

package main import ( "bytes" "fmt" ) func main() { var buffer bytes.Buffer // Writing to buffer buffer.WriteString("Hello, ") buffer.WriteString("World!") // Reading from buffer result := buffer.String() fmt.Println(result) // Output: Hello, World! // Resetting buffer buffer.Reset() fmt.Println(buffer.Len()) // Output: 0 }
