type Writer ¶

type Writer []byte

Writer is a simple byte writer that does not allow extending the buffer.

Writes always go after the current len() and will fail if the slice capacity is too low.

The correct way to use this is to create a slice with sufficient capacity and zero length:

x := make([]byte, 0, 11)
w := (*Writer)(&x)
w.Write([]byte("hello"))
w.WriteByte(' ')
w.WriteString("world")
fmt.Println(string(x)) // "hello world"

package main

import (
	"fmt"

	"go.mau.fi/util/exbytes"
)

func main() {
	x := make([]byte, 0, 11)
	w := (*exbytes.Writer)(&x)
	w.Write([]byte("hello"))
	w.WriteByte(' ')
	w.WriteString("world")
	fmt.Println(string(x))
}

hello world
