Struct rustc_middle::hir::place::Place[][src]

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 rustc_middle::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>[src]

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

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>[src]

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

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

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