bytes.Equal() function is used to check whether two byte slices are same length and contain the same bytes in go.
Equal() built-in function of bytes package or bytes.Equal() function takes two byte slices as arguments and check whether they are equal or not by comparing them.
bytes.Equal() function prototype:
func Equal(a, b []byte) bool or func Equal(a []byte, b []byte) bool Input parameters: a: byte slice b: byte slice Return: It returns true if both the byte slices are equal else false.
Explanation:
1)
a := []byte("abcd")
b := []byte("abcd")
Output: true, since both the byte slices are equal.
2)
a := []byte("abcd")
b := []byte("xyza")
Output: false, since both the byte slices are not equal.
3)
a := []byte{10, 20, 30}
b := []byte{10, 20, 30}
Output: true, since both the byte slices are equal.
4)
a := []byte("去是伟大的!")
b := []byte("去是伟大的!")
Output: true, since both the byte slices are equal.
Example:
package main
import (
"bytes"
"fmt"
)
// main function
func main() {
// Both the byte slices are equal
a := []byte("abcd")
b := []byte("abcd")
fmt.Println(bytes.Equal(a, b))
// Both the byte slices are not equal
a = []byte("abcd")
b = []byte("xyza")
fmt.Println(bytes.Equal(a, b))
// Both the byte slices are equal
a = []byte{10, 20, 30}
b = []byte{10, 20, 30}
fmt.Println(bytes.Equal(a, b))
// Both the byte slices are equal
a = []byte("去是伟大的!")
b = []byte("去是伟大的!")
fmt.Println(bytes.Equal(a, b))
}
Output:
true false true true
*** Apart from Equal() function, you can also compare two byte slices using string typecast like string(a) == string(b). Here, a and b are two byte slices.
