Module type Strategy

Replacement policy

This dictates when elements will droped from the cache.

Signature

type 'a t
type 'a with_init_args

This type is used to specify the signature of cps_create. For instance if cps_create takes two arguments of types x and y: 


  type 'a with_init_args : x -> y -> 'a
val cps_create : f:(_ t -> 'b) -> 'b with_init_args

cps_create ~f is given in CPS form to enable chaining. (i.e. instead of directly returning a value it applies f to this value).

val touch : 'a t -> 'a -> 'a list

Marks an element as "fresh". Returns a list of elements to be dropped from the store.

val remove : 'a t -> 'a -> unit

Informs the strategy that an element was removed from the store.

val clear : 'a t -> unit

Inform the strategy that all the elements where dropped from the store.
