Enum rustc_middle::mir::visit::MutatingUseContext[−][src]

pub enum MutatingUseContext {
    Store,
    AsmOutput,
    Call,
    Yield,
    Drop,
    Borrow,
    AddressOf,
    Projection,
    Retag,
}

Variants

Store
Expand description

Appears as LHS of an assignment.

AsmOutput
Expand description

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
Expand description

Destination of a call.

Yield
Expand description

Destination of a yield.

Drop
Expand description

Being dropped.

Borrow
Expand description

Mutable borrow.

AddressOf
Expand description

AddressOf for *mut pointer.

Projection
Expand description

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
Expand description

Retagging, a “Stacked Borrows” shadow state operation
