Struct rustc_mir::interpret::MemPlace

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

Fields

ptr: Scalar<Tag>

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: Align

meta: MemPlaceMeta<Tag>

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>

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

Replace ptr tag, maintain vtable tag (if any)

pub fn erase_tag(self) -> MemPlace

pub(in interpret::place) fn from_scalar_ptr(
    ptr: Scalar<Tag>,
    align: Align
) -> Self

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

pub fn to_ref(self) -> Immediate<Tag>

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>
