Rust Self Boxing - fn foo(self: Arc<Self>) ?
Yeah so I found out recently that it's possible to create trait methods beyond the standard Self, &Self, &mut Self.
https://doc.rust-lang.org/reference/items/associated-items.html#methods
// Examples of methods implemented on struct `Example`.
struct Example;
type Alias = Example;
trait Trait { type Output; }
impl Trait for Example { type Output = Example; }
impl Example {
fn by_value(self: Self) {}
fn by_ref(self: &Self) {}
fn by_ref_mut(self: &mut Self) {}
fn by_box(self: Box<Self>) {}
fn by_rc(self: Rc<Self>) {}
fn by_arc(self: Arc<Self>) {}
fn by_pin(self: Pin<&Self>) {}
fn explicit_type(self: Arc<Example>) {}
fn with_lifetime<'a>(self: &'a Self) {}
fn nested<'a>(self: &mut &'a Arc<Rc<Box<Alias>>>) {}
fn via_projection(self: <Example as Trait>::Output) {}
}
