Is the "New Type Idiom/Pattern" the same as a struct with one field?

Question

Given a "New Type"

struct MyState(bool);

and a "normal" struct

struct MyState
{
    value: bool,
}

Are these two structs the same, except for naming self.0 and self.value?

Are they both zero-cost abstractions?

Yes

Tuple structs in general are just structs whose fields don’t have names.
