CONTENT_ADDRESSABLE_STOREMAKER is the signature exposed by content-addressable store backends.
K is the implementation of keys and
V is the implementation of values.
include CONTENT_ADDRESSABLE_STORE with type key = K.t and type value = V.t
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.
The type for content-addressable backend stores. The

The type for keys.
type value = V.t
The type for raw values.

add but allows to specify the key directly. The backend might choose to discared that key and/or can be corrupt if the key scheme is not consistent.
batch t f applies the writes in
