Struct rustc_const_eval::interpret::MemPlace

source · [−]

pub struct MemPlace<Tag: Provenance = AllocId> {
    pub ptr: Pointer<Option<Tag>>,
    pub align: Align,
    pub meta: MemPlaceMeta<Tag>,
}

Fields

ptr: Pointer<Option<Tag>>

The pointer can be a pure integer, with the None tag.

align: Alignmeta: 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

source

impl<Tag: Provenance> MemPlace<Tag>

source

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

source

pub fn map_provenance(self, f: impl FnOnce(Option<Tag>) -> Option<Tag>) -> Self

Adjust the provenance of the main pointer (metadata is unaffected).

source

pub fn to_ref(self, cx: &impl HasDataLayout) -> 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.

source

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

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.
