Variants

`Store`

Appears as LHS of an assignment.

`AsmOutput`

Output operand of an inline assembly block.

`Call`

Destination of a call.

`Yield`

Destination of a yield.

`Drop`

Being dropped.

`Borrow`

Mutable borrow.

`AddressOf`

AddressOf for *mut pointer.

`Projection`

Used as base for another place, e.g., x in x.y. Could potentially mutate the place. For example, the projection x.y is marked as a mutation in these cases:

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

`Retag`

Retagging, a “Stacked Borrows” shadow state operation
