sep is used in the array's chunk key encoding.dimension_names and user attributes attributes are included in it's metadata document.codecs.shape and chunk shape chunks.kind and fill value fv.val metadata : t -> Zarr.Node.Array.t -> Zarr.Metadata.Array.tmetadata node t returns the metadata of array node node.
val delete : t -> Zarr.Node.Array.t -> unitdelete t n erases array node n from store t. If node n is not a member of store t then this is a no-op.
val exists : t -> Zarr.Node.Array.t -> boolexists t n returns true if array node n is a member of store t and false otherwise.

val reshape : t -> Zarr.Node.Array.t -> int list -> unitreshape t n shape resizes array node n of store t into new size shape. Note that when the resizing involves shrinking an array along any dimensions, any old unreachable chunks that fall outside of the array's new shape are deleted from the store.
val rename : t -> Zarr.Node.Array.t -> string -> unitrename t n name changes the name of array node n in store t to name.
