pub enum VarDebugInfoContents<'tcx> {

Variants

Place(Place<'tcx>)

This Place only contains projection which satisfy can_use_in_debuginfo.

Const(Constant<'tcx>)

Composite

Fields

ty: Ty<'tcx>

Type of the original user variable. This cannot contain a union or an enum.

fragments: Vec<VarDebugInfoFragment<'tcx>, Global>

All the parts of the original user variable, which ended up in disjoint places, due to optimizations.

The user variable’s data is split across several fragments, each described by a VarDebugInfoFragment. See DWARF 5’s “2.6.1.2 Composite Location Descriptions” and LLVM’s DW_OP_LLVM_fragment for more details on the underlying debuginfo feature this relies on.
