Predicate on a structure field or array element, which is supposed to be true at all times.

Sourceval evaluate_mutval : mutval -> t -> t

given a mutval, evaluate the value of the associated predicate

Sourceval init_mutval : t -> t
Sourceval is_true : t -> bool

check if a predicate can be immediately reduced to true, this is not trivial since mutval exists

Sourceval true_ : t

returns the true predicate

Sourceval equal : t -> t -> bool
Sourceval pp_binop : Format.formatter -> binop -> unit
Sourceval pp_cmpop : Format.formatter -> cmpop -> unit
Sourceval pp : Format.formatter -> t -> unit
Sourceval array_length_to_expr : array_length -> expr
Sourceval conjunction : t -> t -> t

Conjoint two predicate. Ignores true (void) predicates
