Module Irmin_mem.Content_addressableSource

An in-memory store for content-addressable values.

A content-addressable store is an indexed read-write store in which values are keyed directly by their hashes.

Parameters

Signature

Read-only stores

Read-only stores are store where it is only possible to read existing values.

Sourcetype -'a t

The type for stores. The 'a phantom type carries information about the store mutability.

Sourcetype key = Hash.t

The type for keys.

Sourcetype value = Value.t

The type for raw values.

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

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

Sourceval 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.

Sourceval add : [> Irmin.Perms.write ] t -> value -> key Lwt.t

Write the contents of a value to the store. It's the responsibility of the content-addressable store to generate a consistent key.

Sourceval unsafe_add : [> Irmin.Perms.write ] t -> key -> value -> unit Lwt.t

Same as add but allows specifying the key directly. The backend might choose to discard that key and/or can be corrupt if the key scheme is not consistent.

Sourceval close : 'a t -> unit Lwt.t

close t frees up all the resources associated with t. Any operations run on a closed handle will raise Closed.

batch t f applies the writes in f in a separate batch. The exact guarantees depend on the implementation.

Sourceval v : Irmin__.Conf.t -> Irmin.Perms.read t Lwt.t

v config is a function returning fresh store handles, with the configuration config, which is provided by the backend.
