Module Storage.MemoryStore

An Eio-aware in-memory storage backend for Zarr v3 hierarchy.

include Zarr.Storage.STORE with module Deferred = Deferred
module Deferred = Deferred
type t

The storage type.

module Group : sig ... end
module Array : sig ... end
val hierarchy : t -> (Zarr.Node.Array.t list * Zarr.Node.Group.t list) Deferred.t

hierarchy t returns p where p is a pair of lists representing all nodes in store t. The first element of the pair is a list of all array nodes, and the second element is a list of all group nodes. This operation returns a pair of empty lists if store t is empty.

  • raises Parse_error

    if any node has invalid node_type metadata.

val clear : t -> unit Deferred.t

clear t clears the store t by deleting all nodes. If the store is already empty, this is a no-op.

val create : unit -> t

create () returns a new In-memory Zarr store type.
