No, I mean why not define string and slice as
type string struct {
underlyingString *struct {
data *byte
len int
}
}
type slice struct {
underlyingSlice *struct {
underlyingElements unsafe.Pointer
len int
cap int
}
}
instead of the current:
type string struct {
data *byte
len int
}
type slice struct {
underlyingElements unsafe.Pointer
len int
cap int
}
