Module Incremental_kernel.Incremental.S.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
include sig ... end
val sexp_of_t : ('a ‑> Sexplib.Sexp.t) ‑> 'a t ‑> Sexplib.Sexp.t
include Core_kernel.Invariant.S1 with type a t := a t
type 'a t
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.
