Storage.Append_onlyinclude Append_only_intf.S with type key = K.t and type value = V.tAppend-only stores are store where it is possible to read and add new values.
Read-only stores are store where it is only possible to read existing values.
type key = K.tThe type for keys.
type value = V.tThe type for raw values.
val mem : [> Import.read ] t -> key -> boolmem t k is true iff k is present in t.
val find : [> Import.read ] t -> key -> value optionfind t k is Some v if k is associated to v in t and None is k is not present in t.
val add : [> Import.write ] t -> key -> value -> unitWrite the contents of a value to the store.
val close : 'a t -> unitclose t frees up all the resources associated with t. Any operations run on a closed handle will raise Closed.
val batch : Import.read t -> ([ Import.read | Import.write ] t -> 'a) -> 'abatch t f applies the writes in f in a separate batch. The exact guarantees depend on the implementation.
val init : Conf.t -> Import.read tinit config is a function returning fresh store handles, with the configuration config, which is provided by the backend.
