Enum rustc_middle::mir::interpret::GlobalAlloc

pub enum GlobalAlloc<'tcx> {
    Function(Instance<'tcx>),
    Static(DefId),
    Memory(&'tcx Allocation),
}

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.

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(&'tcx Allocation)

The alloc ID points to memory.

Implementations

impl<'tcx> GlobalAlloc<'tcx>

pub fn unwrap_memory(&self) -> &'tcx Allocation

Panics if the GlobalAlloc does not refer to an GlobalAlloc::Memory

pub fn unwrap_fn(&self) -> Instance<'tcx>

Panics if the GlobalAlloc is not GlobalAlloc::Function
