Expand description

Reader-held fractional permission split from an RcuLeaseAccumulator.

Implementations§

Source§

impl<T> RcuReadLease<T>

Source

pub closed spec fn id(self) -> Loc

Storage-protocol identity of the originating accumulator.

Source

pub closed spec fn resource(self) -> T

The resource protected by this lease.

Source

pub closed spec fn fraction(self) -> real

Rational fraction carried by this lease.

Source

pub proof fn tracked_borrow(tracked &self) -> tracked resource : &T

ensures
*resource == self.resource(),

Borrows the protected resource for the lifetime of this lease borrow.

Source

pub proof fn lemma_fraction_bounded(tracked &self)

ensures
0real < self.fraction() <= 1real,

Establishes that every lease carries a positive rational fraction.
