Enum rustc_const_eval::interpret::place::Place
source · pub enum Place<Prov: Provenance = AllocId> {
Ptr(MemPlace<Prov>),
Local {
frame: usize,
local: Local,
},
}
Variants
Ptr(MemPlace<Prov>)
A place referring to a value allocated in the Memory
system.
Local
To support alloc-free locals, we are able to write directly to a local.
(Without that optimization, we’d just always be a MemPlace
.)

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.
