Struct rustc_middle::hir::place::Place

pub struct Place<'tcx> {
    pub base_ty: Ty<'tcx>,
    pub base: PlaceBase,
    pub projections: Vec<Projection<'tcx>>,
}

A Place represents how a value is located in memory.

This is an HIR version of mir::Place

Fields

base_ty: Ty<'tcx>

The type of the PlaceBase

base: PlaceBase

The "outermost" place that holds this value.

projections: Vec<Projection<'tcx>>

How this place is derived from the base place.

Implementations

impl<'tcx> Place<'tcx>

pub fn deref_tys(&self) -> impl Iterator<Item = Ty<'tcx>> + '_

Returns an iterator of the types that have to be dereferenced to access the Place.

The types are in the reverse order that they are applied. So if x: &*const u32 and the Place is **x, then the types returned are *const u32 then &*const u32.

pub fn ty(&self) -> Ty<'tcx>

Returns the type of this Place after all projections have been applied.

pub fn ty_before_projection(&self, projection_index: usize) -> Ty<'tcx>

Returns the type of this Place immediately before projection_indexth projection is applied.

Trait Implementations

impl<'tcx> Clone for Place<'tcx>

pub fn clone(&self) -> Place<'tcx>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'tcx> Debug for Place<'tcx>

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

Formats the value using the given formatter.

impl<'tcx> Eq for Place<'tcx>

impl<'tcx> Hash for Place<'tcx>

pub fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

pub fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher,

    __hasher: &mut StableHasher
)
