Variants§
No
Use this variant when whatever you are converting with as_operand
is the last thing you are converting. This means that if we introduced
an intermediate temporary, we’d only read it immediately after, so we can
also avoid it.
Maybe
For all cases where you aren’t sure or that are too expensive to compute for now. It is always safe to fall back to this.
