Variants

Compact

Compact: data stored inline in the message.

Fields

data: Vec<u8>

The inline raw data bytes.

Contiguous

Contiguous: data stored at a single address in the file.

Fields

address: Option<u64>

File address of the data, or None if undefined (all 0xFF).

size: u64

Size of the data in bytes.

Chunked

Chunked: data stored in chunks via a B-tree.

Fields

chunk_dimensions: Vec<u32>

Chunk dimension sizes.

btree_address: Option<u64>

B-tree address, or None if undefined.

version: u8

Layout version (3 or 4).

chunk_index_type: Option<u8>

Chunk index type (v4 only).

single_chunk_filtered_size: Option<u64>

Filtered size for v4 single chunk with filters.

single_chunk_filter_mask: Option<u32>

Fields

version: u8

Layout version.

Implementations

impl DataLayout

pub fn parse( data: &[u8], offset_size: u8, length_size: u8, ) -> Result<DataLayout, FormatError>

Parse a data layout message from raw message bytes.

offset_size and length_size come from the superblock.
