bytes.ErrTooLarge Variable

The ErrTooLarge variable is an inbuilt variable of the bytes package which indicates that memory cannot be allocated to store data in a buffer. The value of the ErrTooLarge variable is "bytes.Buffer: too large".

Syntax:

*errors.errorString bytes.ErrTooLarge

Implementation in the package source code:

var ErrTooLarge = errors.New("bytes.Buffer: too large")

Parameter(s):

• None

Return Value:

The return type of the bytes.ErrTooLarge variable is a *errors.errorString, it returns the string "bytes.Buffer: too large ".

Example 1:

// Golang program to demonstrate the
// example of bytes.ErrTooLarge Variable

package main

import (
	"bytes"
	"fmt"
)

func main() {
	fmt.Printf("Type of bytes.ErrTooLarge is %T\n",
		bytes.ErrTooLarge)
	fmt.Println("Value of bytes.ErrTooLarge:",
		bytes.ErrTooLarge)
}

Output:

Type of bytes.ErrTooLarge is *errors.errorString
Value of bytes.ErrTooLarge: bytes.Buffer: too large

Example 2:

// Golang program to demonstrate the
// example of bytes.Compare() function

package main

import (
	"bytes"
	"fmt"
)

func main() {
	// Declaring byte slices
	var a = []byte{10, 20, 30, 70, 120, 255}
	var b = []byte{100, 120, 50, 70, 120, 255}
	var c = []byte{10, 20, 30, 70, 120, 255}

	// Comparing byte slices and printing results
	fmt.Println(bytes.Compare(a, b))
	fmt.Println(bytes.Compare(b, c))
	fmt.Println(bytes.Compare(a, c))
}

Output:

-1
