Enum GlobalRef 

pub enum GlobalRef {
    Static(DefId),
    Alloc(AllocId),
}

A global allocation.

Variants

Static(DefId)

A static item.

Alloc(AllocId)

An allocation without a corresponding static item: a referenced constant, a str literal, or a promoted static (e.g. the [1, 2] in static S: &[u8] = &[1, 2]).

Implementations

impl GlobalRef

pub fn mutability(self, tcx: TyCtxt<'_>) -> Mutability

The mutability of this global.

pub fn memory<'tcx>(self, tcx: TyCtxt<'tcx>) -> Option<ConstAllocation<'tcx>>

The memory of this global. Returns None for a static whose evaluation fails, or that has no initializer (in an extern block).
