Variants§

§

Store

Appears as LHS of an assignment.

§

SetDiscriminant

Appears on SetDiscriminant

§

Deinit

Appears on Deinit

§

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

source§

impl PartialEq for MutatingUseContext

source§

fn eq(&self, other: &MutatingUseContext) -> bool
