Enum DataspaceClass 

pub enum DataspaceClass {
    Scalar,
    Simple,
    Null,
}

Which of the three dataspace classes a message describes (H5Osdspace.c’s type byte / H5S_class_t).

Scalar (rank 0, exactly one element) and Null (no elements at all) both carry an empty dims, so the class cannot be inferred from dims alone — it must be tracked explicitly, matching upstream’s dedicated type field.

Variants

Scalar

Rank 0: a single element, no dimensions.

Simple

Rank >= 1: an ordinary N-dimensional dataspace.

Null

No elements at all (H5Screate(H5S_NULL)) — distinct from a scalar or from a Simple dataspace with a zero-length dimension.
