How to use the strconv.AppendQuoteRuneToASCII() function in Go
Maria ElijahOverview
The strconv package’s AppendQuoteRuneToASCII() function is used to append the single-quoted Go character literal, representing r (as generated by the QuoteRuneToASCII() function) to dst and returns the extended buffer.
Syntax
func AppendQuoteRuneToASCII(dst []byte, r rune) []byte
Parameters
dstis a byte array to which the single-quoted character is to be appended literal.ris the rune character to be appended.
Return value
The function AppendQuoteRuneToASCII() returns the extended buffer after appending the single-quoted character.
Example
The following code shows how to implement the AppendQuoteRuneToASCII() function in Go.
// Using strconv.AppendQuoteRuneToASCII() Function
package main
import (
"fmt"
"strconv"
)
func main() {
x := []byte("Empty")
fmt.Println("Orignal value before AppendQuoteRuneToASCII()", string(x))
fmt.Println()
// Append a character (rune 108 is the Unicode of l)
x = strconv.AppendQuoteRuneToASCII(x, 108)
fmt.Println("The new value after AppendQuoteRuneToASCII()", string(x))
fmt.Println()
// Append emoji
x = strconv.AppendQuoteRuneToASCII(x, '🥰')
x = strconv.AppendQuoteRuneToASCII(x, '🙉')
fmt.Println("The new Values in the array after AppendQuoteRuneToASCII()", string(x))
fmt.Println()
}Explanation
- Line 4: We add the package
main. - Lines 6–9: We import the necessary packages in the Go project.
- Lines 11–21: We define the
main()function, the variablerof the type rune, assign a value to it, and pass the variable in theAppendQuoteRuneToASCII()function. This returns a single-quoted Go character literal, representing the given rune value. Finally, we display the result.
Note: All the values assigned to variable
xare appended to thedst.
