Struct ChunkDescriptor 

pub struct ChunkDescriptor { /* private fields */ }

Stable global identity and compact local extent of one chunk.

Implementations

impl ChunkDescriptor

pub fn new( dataset: DatasetId, chunk: ChunkId, logical_start: LogicalRow, rows: u32, ) -> Result<Self, ProviderError>

Creates a chunk descriptor.

Errors

Rejects a logical range whose end exceeds u64.

pub const fn dataset(self) -> DatasetId

Dataset identity.

pub const fn chunk(self) -> ChunkId

Chunk identity.

pub const fn logical_start(self) -> LogicalRow

First global row represented by local row zero.

pub const fn rows(self) -> u32

Number of locally addressable rows.

pub fn resolve(self, local: LocalRow) -> Result<LogicalRow, ProviderError>

Resolves a compact local row to its stable global row.

Errors

Returns a typed error when the local row lies outside this chunk.
