Variants

Store

Appears as LHS of an assignment.

AsmOutput

Can often be treated as a Store, but needs to be separate because ASM is allowed to read outputs as well, so a Store-AsmOutput sequence cannot be simplified the way a Store-Store can be.

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

Layout

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.
