PointsTo

vstd::cell::pcell_maybe_uninit

Struct PointsTo 

Source 
pub struct PointsTo<V>(/* private fields */);
Expand description

Permission object associated with a PCell<V>.

See the documentation of PCell<V> for more information.

Implementations§

Source§

impl<V> PointsTo<V>

Source

pub closed spec fn id(&self) -> CellId

The CellId of the PCell this permission is associated with.

Source

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

The contents of the cell.

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)

Source

pub proof fn is_exclusive(tracked &mut self, tracked other: &PointsTo<V>)

ensures
*self == *old(self),
self.id() != other.id(),

Guarantees that two permissions can not be associated with the same CellId.
