Struct rustc_const_eval::interpret::place::PlaceTy

pub struct PlaceTy<'tcx, Tag: Provenance = AllocId> {
    place: Place<Tag>,
    pub layout: TyAndLayout<'tcx>,
    pub align: Align,
}

Fields

place: Place<Tag>

layout: TyAndLayout<'tcx>

align: Align

rustc does not have a proper way to represent the type of a field of a repr(packed) struct: it needs to have a different alignment than the field type would usually have. So we represent this here with a separate field that “overwrites” layout.align. This means layout.align should never be used for a PlaceTy!

Implementations

impl<'tcx, Tag: Provenance> PlaceTy<'tcx, Tag>

pub fn try_as_mplace(&self) -> Result<MPlaceTy<'tcx, Tag>, (usize, Local)>

A place is either an mplace or some local.

pub fn assert_mem_place(&self) -> MPlaceTy<'tcx, Tag>

Methods from Deref<Target = Place<Tag>>

pub fn assert_local(&self) -> (usize, Local)

Asserts that this points to some local variable. Returns the frame idx and the variable idx.

Trait Implementations

impl<'tcx, Tag: Clone + Provenance> Clone for PlaceTy<'tcx, Tag>

fn clone(&self) -> PlaceTy<'tcx, Tag>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'tcx, Tag: Debug + Provenance> Debug for PlaceTy<'tcx, Tag>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'tcx, Tag: Provenance> Deref for PlaceTy<'tcx, Tag>

type Target = Place<Tag>

The resulting type after dereferencing.

fn deref(&self) -> &Place<Tag>

Dereferences the value.

impl<'tcx, Tag: Provenance> From<&MPlaceTy<'tcx, Tag>> for PlaceTy<'tcx, Tag>

fn from(mplace: &MPlaceTy<'tcx, Tag>) -> Self

Converts to this type from the input type.

impl<'tcx, Tag: Provenance> From<&mut MPlaceTy<'tcx, Tag>> for PlaceTy<'tcx, Tag>

fn from(mplace: &mut MPlaceTy<'tcx, Tag>) -> Self

Converts to this type from the input type.

impl<'tcx, Tag: Provenance> From<MPlaceTy<'tcx, Tag>> for PlaceTy<'tcx, Tag>

fn from(mplace: MPlaceTy<'tcx, Tag>) -> Self

Converts to this type from the input type.

impl<'tcx, Tag: Copy + Provenance> Copy for PlaceTy<'tcx, Tag>

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.
