sourcefn memory_ty(&self, cx: &CodegenCx<'ll, 'tcx>) -> &'ll Type
fn memory_ty(&self, cx: &CodegenCx<'ll, 'tcx>) -> &'ll Type
Gets the LLVM type for a place of the original Rust type of
this argument/return, i.e., the result of type_of::type_of.

&self,
bx: &mut Builder<'_, 'll, 'tcx>,

)
fn store(
&self,
bx: &mut Builder<'_, 'll, 'tcx>,
val: &'ll Value,
dst: PlaceRef<'tcx, &'ll Value>
)
Stores a direct/indirect value described by this ArgAbi into a place for the original Rust type of this argument/return. Can be used for both storing formal arguments into Rust variables or results of call/invoke instructions into their destinations.

Layout
Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
