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

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
