type t

A cache of clusters

val create : 
  read_cluster:
    (Qcow_types.Cluster.t ->
      (Cstruct.t, Mirage_block.error) Pervasives.result Lwt.t) ->
  write_cluster:
    (Qcow_types.Cluster.t ->
      Cstruct.t ->
      (unit, Mirage_block.write_error) Pervasives.result Lwt.t) ->
  unit ->
  t

Create a cache of clusters, given the read/write functions

val read : 
  t ->
  Qcow_types.Cluster.t ->
  (Cstruct.t, Mirage_block.error) Pervasives.result Lwt.t

read t cluster returns the data in cluster

val write : 
  t ->
  Qcow_types.Cluster.t ->
  Cstruct.t ->
  (unit, Mirage_block.write_error) Pervasives.result Lwt.t

write t cluster data writes data to cluster

val remove : t -> Qcow_types.Cluster.t -> unit

remove t cluster drops any cache associated with cluster

val resize : t -> Qcow_types.Cluster.t -> unit

resize t new_size_clusters drops any cache entries which are beyond the new file size.
