Struct rustc_mir::interpret::place::MemPlace[−][src]

pub struct MemPlace<Tag = ()> {
    pub ptr: Scalar<Tag>,
    pub align: Align,
    pub meta: MemPlaceMeta<Tag>,
}

Fields

ptr: Scalar<Tag>
Expand description

A place may have an integral pointer for ZSTs, and since it might be turned back into a reference before ever being dereferenced. However, it may never be uninit.

align: Alignmeta: MemPlaceMeta<Tag>
Expand description

Metadata for unsized places. Interpretation is up to the type. Must not be present for sized types, but can be missing for unsized types (e.g., extern type).

Implementations

impl<Tag> MemPlace<Tag>[src]

pub fn replace_tag(self, new_tag: Tag) -> Self[src]

Replace ptr tag, maintain vtable tag (if any)

pub fn erase_tag(self) -> MemPlace[src]

fn from_scalar_ptr(ptr: Scalar<Tag>, align: Align) -> Self[src]

pub fn from_ptr(ptr: Pointer<Tag>, align: Align) -> Self[src]

pub fn to_ref(self) -> Immediate<Tag>[src]

Turn a mplace into a (thin or wide) pointer, as a reference, pointing to the same space. This is the inverse of ref_to_mplace.

pub fn offset<'tcx>(
    self,
    offset: Size,
    meta: MemPlaceMeta<Tag>,
    cx: &impl HasDataLayout
) -> InterpResult<'tcx, Self>[src]
