module Dep: sig end
Iterators over dependency index.
type eqs
val iter : eqs -> (Fact.Equal.t -> unit) -> Term.t -> unit
iter s f y
applies f
to each equality e
of the
form x = a
with justification rho
such that x
is dependent on y
.
val fold : eqs -> (Fact.Equal.t -> 'a -> 'a) -> Term.t -> 'a -> 'a
fold s f y e
accumulates, starting with e
, applications
of f
to each equality x = a
which x
dependent on y
.
val for_all : eqs -> (Fact.Equal.t -> bool) -> Term.t -> bool
for_all s p y
holds iff p e
holds for all equalities
x = a
with x
dependent on y
.
val exists : eqs -> (Fact.Equal.t -> bool) -> Term.t -> bool
exists s p y
holds iff p e
holds for all equalities
x = a
with x
dependent on y
.
val choose : eqs -> (Fact.Equal.t -> bool) -> Term.t -> Fact.Equal.t
choose s y
returns equality e
of the form x = a
if x
is dependent on y
; otherwise, Not_found
is raised.
