module S : APPEND_ONLY_STORE_MAKERinclude CONTENT_ADDRESSABLE_STORE
with type 'a t = 'a S(K)(V).t
and type key = K.t
and type value = V.tContent-addressable stores are store where it is possible to read and add new values. Keys are derived from the values raw contents and hence are deterministic.
type 'a t = 'a S(K)(V).tThe type for content-addressable backend stores. The 'a phantom type carries information about the store mutability.
type key = K.tThe type for keys.
type value = V.tThe type for raw values.
val mem : [> Perms.read ] t -> key -> bool Lwt.tmem t k is true iff k is present in t.
val find : [> Perms.read ] t -> key -> value option Lwt.tfind t k is Some v if k is associated to v in t and None is k is not present in t.
val add : [> Perms.write ] t -> value -> key Lwt.tWrite the contents of a value to the store. It's the responsibility of the content-addressable store to generate a consistent key.
val batch :
Perms.read t ->
([ Perms.read | Perms.write ] t -> 'a Lwt.t) ->
'a Lwt.tbatch t f applies the writes in f in a separate batch. The exact guarantees depend on the implementation.
val v : Irmin__.Conf.t -> Perms.read t Lwt.tv config is a function returning fresh store handles, with the configuration config, which is provided by the backend.
