Struct CpuLocal Points ToSet &nbsp; Copy item path

impl<V> CpuLocalPointsToSet<V>

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

Identity of the corresponding CpuLocalAuth.

pub open spec fn cpus(&self) -> Set<CpuId>

{ self@.dom() }

CPUs whose exclusive points-to resources are still held here.

pub open spec fn contains(&self, cpu: CpuId) -> bool

{ self.cpus().contains(cpu) }

Whether this collection currently owns cpu’s points-to resource.

pub proof fn tracked_take(tracked &mut self, cpu: CpuId) -> tracked res : CpuLocalPointsTo<V>

requires

old(self).contains(cpu),

ensures

final(self).id() == old(self).id(),

res.id() == final(self).id(),

res.cpu() == cpu,

res.value() == old(self)@[cpu],

final(self)@ == old(self)@.remove(cpu),

final(self).cpus() == old(self).cpus().remove(cpu),

Splits out exclusive ownership of one CPU’s entry.

pub proof fn tracked_return(tracked &mut self, tracked points_to: CpuLocalPointsTo<V>)

requires

old(self).id() == points_to.id(),

!old(self).contains(points_to.cpu()),

ensures

final(self).id() == old(self).id(),

final(self)@ == old(self)@.insert(points_to.cpu(), points_to.value()),

final(self).cpus() == old(self).cpus().insert(points_to.cpu()),

Returns an individual points-to resource to this collection.
