Module Irmin_mem.Append_onlySource
An in-memory store for append-only values.
Parameters
module K : Irmin.Type.Smodule V : Irmin.Type.SSignature
Append-only stores
Append-only stores are store where it is possible to read and add new values.
Read-only stores
Read-only stores are store where it is only possible to read existing values.
The type for stores. The 'a phantom type carries information about the store mutability.
mem t k is true iff k is present in t.
find t k is Some v if k is associated to v in t and None is k is not present in t.
Write the contents of a value to the store.
close t frees up all the resources associated with t. Any operations run on a closed handle will raise Closed.
val batch :
Irmin.Perms.read t ->
([ Irmin.Perms.read | Irmin.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.
v config is a function returning fresh store handles, with the configuration config, which is provided by the backend.
