Module type Immediate.Intern_table

module Stats : sig ... end
val grow_by : int -> unit

grow_by n ensures that the intern table can hold at least n additional entries without resizing (again). This is useful for applications which must not pause online for the (substantial) time required to rehash a large intern table.

val after_grow : (before:Core.Time_ns.t -> len_before:int -> len:int -> unit) -> unit

after_grow f registers a growth logger. f will be called immediately after every growth of the intern table, with the time and size before and the size after.

f would typically call Time_ns.now to learn the time after.
