Variants

`Inspect`

Being inspected in some way, like loading a len.

`Copy`

Consumed as part of an operand.

`Move`

Consumed as part of an operand.

`SharedBorrow`

Shared borrow.

`ShallowBorrow`

Shallow borrow.

`UniqueBorrow`

Unique borrow.

`AddressOf`

AddressOf for *const pointer.

`Projection`

Used as base for another place, e.g., x in x.y. Will not mutate the place. For example, the projection x.y is not marked as a mutation in these cases:

z = x.y;
f(&x.y);
