Struct DataObjectDescriptor 

pub struct DataObjectDescriptor {
    pub obj_type: String,
    pub ndim: u64,
    pub shape: Vec<u64>,
    pub strides: Vec<u64>,
    pub dtype: Dtype,
    pub byte_order: ByteOrder,
    pub encoding: String,
    pub filter: String,
    pub compression: String,
    pub params: BTreeMap<String, Value>,
    pub hash: Option<HashDescriptor>,
}

Per-object descriptor — merges tensor metadata and encoding instructions.

Each data object frame carries one of these as its CBOR descriptor. This replaces the v1 split between ObjectDescriptor (tensor info) and PayloadDescriptor (encoding info).

Fields

obj_type: String

ndim: u64

shape: Vec<u64>

strides: Vec<u64>

dtype: Dtype

byte_order: ByteOrder

encoding: String

filter: String

compression: String

params: BTreeMap<String, Value>

Encoding/filter/compression parameters (reference_value, bits_per_value, szip_block_offsets, etc.). Stored as ciborium::Value for flexibility.

hash: Option<HashDescriptor>

Per-object integrity hash (set during encoding).
