将strconv.ParseInt与int一起使用的惯用方式

Question

I end up writing code like this. I need a regular int (for some other function call), but parseInt only produces 64 bit ints:

i64, err := strconv.ParseInt(s, 10, 0)
if err != nil {
    fmt.Println("parsing failed for", s)
}
i := int(i64)

Is there a way to avoid the extra cast? Or a way to make this more idiomatic?

Answer 1

You can use strconv.Atoi which wraps strconv.ParseInt in a way you want.
