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 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(),
        value: option_from_mem_contents(self.mem_contents()),
    }
}
source

pub open spec fn opt_value(&self) -> Option<V>

👎Deprecated: use mem_contents() instead
{
    match self.mem_contents() {
        MemContents::Init(value) => Some(value),
        MemContents::Uninit => None,
    }
}
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)
