Module `1-Incr.State`

State

Each call to Incremental.Make creates shared state used by all the incremental functions.

type t

val sexp_of_t : t -> Ppx_sexp_conv_lib.Sexp.t

invariant checks invariants of all necessary nodes, as well as other data structures used for stabilization.

include Core_kernel.Invariant.S with type t := t

type t

val invariant : t Base__.Invariant_intf.inv

val t : t: t is the shared state for this call to Incremental.Make.

val max_height_allowed : t -> int
val set_max_height_allowed : t -> int -> unit: set_max_height_allowed t height sets the maximum allowed height of nodes. set_max_height_allowed raises if called during stabilization, or if height < max_height_seen t.

val num_active_observers : t -> int: num_active_observers returns (in constant time) the number of observers that have been created and not yet disallowed (either explicitly or via finalization).

val max_height_seen : t -> int: constant-time stats.

val num_nodes_became_necessary : t -> int
val num_nodes_became_unnecessary : t -> int
val num_nodes_changed : t -> int
val num_nodes_created : t -> int
val num_nodes_invalidated : t -> int
val num_nodes_recomputed : t -> int
val num_nodes_recomputed_directly_because_one_child : t -> int
val num_nodes_recomputed_directly_because_min_height : t -> int
val num_stabilizes : t -> int
val num_var_sets : t -> int
