Enum AttributeStorage 

pub enum AttributeStorage {
    Compact,
    Dense,
}

Where an object’s attributes physically live: inline as Attribute messages in the object header (Compact), or split into a fractal heap plus a v2 B-tree name index once the set has grown past H5O__attr_create’s phase-change threshold (Dense). Mirrors h5py’s h5py.h5o.get_info(...).meta_size.attr.index_size check: nonzero means dense.

Variants

Compact

Attribute messages sit directly in the object header.

Dense

Attributes live in a fractal heap, indexed by a v2 B-tree.
