Module `Make.Cutoff`

An 'a Cutoff.t is a function that returns true if propagation of changes should be cutoff at a node based on the old value and the (possible) new value of the node.

type 'a t

val sexp_of_t : ('a -> Ppx_sexp_conv_lib.Sexp.t) -> 'a t -> Ppx_sexp_conv_lib.Sexp.t

include Core_kernel.Invariant.S1 with type 'a t := 'a t

type 'a t

val invariant : 'a Base__.Invariant_intf.inv -> 'a t Base__.Invariant_intf.inv

val create : (old_value:'a -> new_value:'a -> bool) -> 'a t
val of_compare : ('a -> 'a -> int) -> 'a t
val always : _ t
val never : _ t
val phys_equal : _ t
val poly_equal : _ t
val should_cutoff : 'a t -> old_value:'a -> new_value:'a -> bool
val equal : 'a t -> 'a t -> bool: One can use equal in combination with get_cutoff to check if a node has a particular cutoff function. equal uses Core.phys_equal for functional values supplied to create and of_compare.
