string(x)-alike expressions where x is an integer but not byte or rune.
Such conversions are discouraged because they return the UTF-8 representation
of the Unicode code point x, and not a decimal string representation
of x as one might expect. Furthermore, if x denotes
an invalid code point, the conversion cannot be statically rejected.
For conversions that intend on using the code point, consider replacing them
with string(rune(x)). Otherwise, strconv.Itoa
and its equivalents return the string representation of the value in the desired
base.
Example:
func main() {
a := 1
_ = string(a)
}After the Convert integer to rune quick-fix is applied:
func main() {
a := 1
_ = string(rune(a))
}
