Struct BondChunkProvider 

pub struct BondChunkProvider { /* private fields */ }

Zero-copy provider for regularly paged chemical bond topology.

Implementations

impl BondChunkProvider

pub fn new( dataset: DatasetId, first_chunk: ChunkId, atom_dataset: DatasetId, atom_logical_start: LogicalRow, structure: Structure, ) -> Result<Self, ProviderError>

Creates a provider using the default bounded bond payload size.

Errors

Rejects unavailable topology and identity or chunk-range overflow.

pub fn with_rows_per_chunk( dataset: DatasetId, first_chunk: ChunkId, atom_dataset: DatasetId, atom_logical_start: LogicalRow, structure: Structure, rows_per_chunk: u32, ) -> Result<Self, ProviderError>

Creates a provider with an explicit bounded payload row count.

Errors

Rejects zero chunk rows, unavailable topology, or identity overflow.

pub const fn dataset(&self) -> DatasetDescriptor

Compact dataset metadata; no per-chunk index is retained.

pub fn chunk(&self, chunk: ChunkId) -> Result<BondChunk, ProviderError>

Produces one shared topology payload in O(1), without a table scan.

Errors

Rejects chunk identities outside this provider or source index overflow.
