What is the strconv.AppendQuoteRuneToGraphic() function in Go?
Overview
The AppendQuoteRuneToGraphic() function of the strconv package is used to append the single-quoted Go character literal that represents r (as generated by the QuoteRuneToGraphic() function) to dst and then return the extended buffer.
Note: The parameter
dstis of type[]byteandris of the typerune.
Syntax
func AppendQuoteRuneToGraphic(dst []byte, r rune) []byte
Parameter values
dst: This is a byte array to which the single-quoted character is to be appended.r: This is the rune character that is to be appended.
Return value
The AppendQuoteRuneToGraphic() function returns the extended buffer after appending the single-quoted character to dst.
Example
The following code shows us how to implement the AppendQuoteRuneToGraphic() function in Golang.
// Using strconv.AppendQuoteRuneToGraphic() Functionpackage mainimport ("fmt""strconv")func main() {x := []byte("QuoteRuneToGraphic:")fmt.Println("Orignal value before AppendQuoteRuneToGraphic()", string(x))fmt.Println()// Append a character (rune 108 is the Unicode of l)x = strconv.AppendQuoteRuneToGraphic(x, 108)fmt.Println("The new Value after AppendQuoteRuneToGraphic()", string(x))fmt.Println()// Append emojix = strconv.AppendQuoteRuneToGraphic(x, '🙉')fmt.Println("The new Value after AppendQuoteRuneToGraphic()", string(x))fmt.Println()// Append emojix = strconv.AppendQuoteRuneToGraphic(x, '🙊')// Append a character (rune 95 is the Unicode of _)x = strconv.AppendQuoteRuneToGraphic(x, 95)fmt.Println("The new Value after AppendQuoteRuneToGraphic()", string(x))}
Explanation
- Line 4: We add the
mainpackage. - Lines 6–9: We import the necessary packages in the Golang project.
- Lines 11–21: We define the
main()function. Then, we define the variablerof typerune, assign a value to it, and pass it to theAppendQuoteRuneToGraphic()function. This returns a single-quoted Go character literal that represents the givenrunevalue. Finally, we display the result.
Note: All the values assigned to the variable
xare appended to thedstof type[]byte.
