Struct PlyChunkSource 

pub struct PlyChunkSource<R: BufRead> { /* private fields */ }

Bounded sequential PLY source for ASCII and little-endian binary vertices.

Implementations

impl<R: BufRead> PlyChunkSource<R>

pub fn new( reader: R, options: StreamOptions, cancellation: CancellationToken, ) -> Result<Self, IoError>

Parses the header and creates a bounded PLY source.

pub fn header(&self) -> &PlyHeader

Returns the parsed header, including the declared vertex count.

impl PlyChunkSource<BufReader<File>>

pub fn open( path: impl AsRef<Path>, options: StreamOptions, cancellation: CancellationToken, ) -> Result<Self, IoError>

Opens a local PLY file for bounded chunk reads.

fn schema(&self) -> &SchemaDescriptor

Schema shared by every emitted record.

fn options(&self) -> &StreamOptions

Validated execution options.

fn memory_tracker(&self) -> &MemoryTracker

Exact tracker shared by emitted chunk leases.

fn cancellation_token(&self) -> CancellationToken

Cooperative cancellation state checked at chunk boundaries.

fn max_chunk_bytes(&self) -> u64
