Enum rustc_mir::shim::Adjustment

enum Adjustment {
    Identity,
    Deref,
    RefMut,
}

Variants

Identity

Pass the receiver as-is.

Deref

We get passed &[mut] self and call the target with *self.

This either copies self (if Self: Copy, eg. for function items), or moves out of it (for VtableShim, which effectively is passed &own Self).

RefMut

We get passed self: Self and call the target with &mut self.

In this case we need to ensure that the Self is dropped after the call, as the callee won’t do it for us.
