Expand description

Data layout message — describes how dataset storage is organized.

Message type 0x0008.

Variants§

§

Compact

Data stored inline in the object header. For very small datasets.

Fields

§data: Bytes

The inline data bytes.

§

Contiguous

Data stored as a single contiguous block in the file.

Fields

§address: u64

Byte offset in the file. UNDEF_ADDR = unallocated.

§size: u64

Total size in bytes.

§

Chunked

Data stored in chunks, with an index structure for lookup.

Fields

§chunk_shape: Vec<u64>

Chunk dimensions in array elements.

§index_address: u64

Address of the chunk index (B-tree or other structure).

§indexing_type: ChunkIndexType

How chunks are indexed.

§flags: u8

Layout flags.

§index_params: ChunkIndexParams

Additional indexing parameters (type-specific).
