Required Methods§

source

spec fn op(self, other: Self) -> Self

source

spec fn rel(self, s: Map<K, V>) -> bool

Note that rel, in contrast to PCM::valid, is not necessarily closed under inclusion.

source

spec fn unit() -> Self

source

proof fn commutative(a: Self, b: Self)

ensures
Self::op(a, b) == Self::op(b, a),
source

proof fn associative(a: Self, b: Self, c: Self)

ensures
Self::op(a, Self::op(b, c)) == Self::op(Self::op(a, b), c),
source

proof fn op_unit(a: Self)

ensures
Self::op(a, Self::unit()) == a,
