Enum paralegal_spdg::rustc::mir::interpret::GlobalAlloc

pub enum GlobalAlloc<'tcx> {
    Function(Instance<'tcx>),
    VTable(Ty<'tcx>, Option<Binder<'tcx, ExistentialTraitRef<'tcx>>>),
    Static(DefId),
    Memory(ConstAllocation<'tcx>),
}

An allocation in the global (tcx-managed) memory can be either a function pointer, a static, or a “real” allocation with some data in it.

Variants

Function(Instance<'tcx>)

The alloc ID is used as a function pointer.

VTable(Ty<'tcx>, Option<Binder<'tcx, ExistentialTraitRef<'tcx>>>)

This alloc ID points to a symbolic (not-reified) vtable.

Static(DefId)

The alloc ID points to a “lazy” static variable that did not get computed (yet). This is also used to break the cycle in recursive statics.

Memory(ConstAllocation<'tcx>)

The alloc ID points to memory.
