Implementations§

Source§

impl<V> PointsTo<V>

Source

pub uninterp fn id(&self) -> CellId

The CellId of the PCell this permission is associated with.

Source

pub uninterp fn mem_contents(&self) -> MemContents<V>

The contents of the cell, either unitialized or initialized to some V.

Source

pub open spec fn view(self) -> PointsToData<V>

{
    PointsToData {
        pcell: self.id(),
        mem_contents: self.mem_contents(),
    }
}
Source

pub open spec fn is_init(&self) -> bool

{ self.mem_contents().is_init() }

Is this cell initialized?

Source

pub open spec fn is_uninit(&self) -> bool

{ self.mem_contents().is_uninit() }

Is this cell uninitialized?

Source

pub open spec fn value(&self) -> V

recommends
self.is_init(),
{ self.mem_contents().value() }

Value of the cell (if initialized)
