Expand description

State of a temporary during collection and promotion.

Variants

`Undefined`

No references to this temp.

`Defined`

Fields

location: Location

uses: usize

One direct assignment and any number of direct uses. A borrow of this temp is promotable if the assigned value is qualified as constant.

`Unpromotable`

Any other combination of assignments/uses.

`PromotedOut`

This temp was part of an rvalue which got extracted during promotion and needs cleanup.
