Enum rustc_const_eval::interpret::LocalValue
source · pub enum LocalValue<Prov: Provenance = AllocId> {
Dead,
Live(Operand<Prov>),
}Expand description
Current value of a local variable
Variants
Dead
This local is not currently alive, and cannot be used at all.
Live(Operand<Prov>)
A normal, live local.
Mostly for convenience, we re-use the Operand type here.
This is an optimization over just always having a pointer here;
we can thus avoid doing an allocation when the local just stores
immediate values and never has its address taken.

Layout
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
