Here, bytes.Runes() function is used to convert byte slice into rune slice in go. It returns slice of runes.
Runes() built-in function of bytes package interprets byte slice as a sequence of UTF-8-encoded code points and returns a slice of runes (Unicode code points) equivalent to byte slice.
bytes.Runes() function prototype:
func Runes(s []byte) []rune Input parameters: s: slice of bytes Return: It returns slice of runes equivalent to byte slice.
Explanation on convert byte slice into rune slice in go
1)
s := []byte("Hello go golang")
Output:
U+0048 'H'
U+0065 'e'
U+006C 'l'
U+006C 'l'
U+006F 'o'
U+0020 ' '
U+0067 'g'
U+006F 'o'
U+0020 ' '
U+0067 'g'
U+006F 'o'
U+006C 'l'
U+0061 'a'
U+006E 'n'
U+0067 'g'
Example:
Code 1:
package main
import (
"bytes"
"fmt"
)
// main function
func main() {
s := []byte("Hello go golang")
rs := bytes.Runes(s)
for _, r := range rs {
fmt.Printf("%#U\n", r)
}
}
Output:
U+0048 'H' U+0065 'e' U+006C 'l' U+006C 'l' U+006F 'o' U+0020 ' ' U+0067 'g' U+006F 'o' U+0020 ' ' U+0067 'g' U+006F 'o' U+006C 'l' U+0061 'a' U+006E 'n' U+0067 'g'
Code 2:
package main
import (
"bytes"
"fmt"
)
// main function
func main() {
s := []byte{10, 20, 30, 40}
rs := bytes.Runes(s)
for _, r := range rs {
fmt.Printf("%#U\n", r)
}
}
Output:
U+000A
U+0014
U+001E
U+0028 '('
