Enum wasmer_vm::store::MaybeInstanceOwned
source · pub enum MaybeInstanceOwned<T> {
Host(Box<UnsafeCell<T>>),
Instance(NonNull<T>),
}
Expand description
Data used by the generated code is generally located inline within the
VMContext
for items defined in an instance. Host-defined objects are
allocated separately and owned directly by the context.
Variants§
Host(Box<UnsafeCell<T>>)
The data is owned here.
Instance(NonNull<T>)
The data is stored inline in the VMContext
of an instance.
