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.

AddressOf

AddressOf for *const pointer.

PlaceMention

PlaceMention statement.

This statement is executed as a check that the Place is live without reading from it, so it must be considered as a non-mutating use.

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);
