include Irmin.CONTENT_ADDRESSABLE_STORE

Content-addressable stores

Content-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

The type for content-addressable backend stores. The 'a phantom type carries information about the store mutability.

type key

The type for keys.

type value

The type for raw values.

val mem : [> Irmin.Perms.read ] t -> key -> bool Lwt.t

mem t k is true iff k is present in t.

val find : [> Irmin.Perms.read ] t -> key -> value option Lwt.t

find t k is Some v if k is associated to v in t and None is k is not present in t.

val clear : 'a t -> unit Lwt.t

Clear the store. This operation is expected to be slow.

val add : 'a t -> value -> key Lwt.t

Overwrite add to work with a read-only database handler.

val unsafe_add : 'a t -> key -> value -> unit Lwt.t

Overwrite unsafe_add to work with a read-only database handler.

val unsafe_append : ensure_unique:bool -> overcommit:bool -> 'a t -> key -> value -> unit
val unsafe_mem : 'a t -> key -> bool
val unsafe_find : check_integrity:bool -> 'a t -> key -> value option
val generation : 'a t -> Optint.Int63.t

The number of times that clear has been called on this store.

val clear_keep_generation : 'a t -> unit Lwt.t
val close : _ t -> unit Lwt.t
val batch : Irmin.Perms.read t -> ([ Irmin.Perms.read | Irmin.Perms.write ] t -> 'a Lwt.t) -> 'a Lwt.t
