intcast identifies integer type casts that can potentially cause overflow.
func f(i int) uint {
return uint(i) // unsafe cast
}intcast also handles casts on defined types.
type MyInt int
func f(i MyInt) uint {
return uint(i) // unsafe cast
}intcast ignores lines with ignore comments.
func f(i int) uint {
//lint:ignore intcast reason
return uint(i)
