package bytes
Reset resets the buffer so it has no content. Buffer.Reset() is the same as Buffer.Truncate(0).
Golang bytes.Buffer.Reset() function usage example
package main
import (
"bytes"
"fmt"
)
func main() {
buff := bytes.NewBuffer([]byte("abcdefg"))
fmt.Printf("%d \n", buff.Len())
// remove all content from the buff buffer
buff.Reset()
fmt.Printf("%d \n", buff.Len())
}
Output :
7
0
