Implementations§

Source§

impl<R> DropObligation<R>

Source

pub closed spec fn value(self) -> R

Source

pub closed spec fn id(self) -> Loc

Unique identifier of this token.

Source

pub proof fn tracked_mint(value: R) -> tracked res : DropObligation<R>

ensures
res.value() == value,

Mint a fresh obligation token. S.

Source

pub proof fn validate_with_other(tracked &mut self, tracked other: &Self)

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

Two outstanding obligations have distinct Locs.
