Struct CopcChunkSource 

pub struct CopcChunkSource<S: ByteSource> { /* private fields */ }

Bounded, deterministic COPC source over any random-access byte source.

Implementations

impl<S: ByteSource> CopcChunkSource<S>

pub fn from_source( source: S, query: Option<CopcQuery>, options: StreamOptions, cancellation: CancellationToken, ) -> Result<Self, IoError>

Opens a byte source, loads matching hierarchy metadata, and orders nodes by (level, x, y, z) for repeatable chunk identities.

pub fn declared_point_count(&self) -> u64

Returns the declared LAS point count from the COPC header.

impl CopcChunkSource<FileSource>

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

Opens a local COPC file for bounded node and record chunk reads.

impl CopcChunkSource<HttpByteSource>

pub fn open_url( url: &str, query: Option<CopcQuery>, options: StreamOptions, cancellation: CancellationToken, ) -> Result<Self, IoError>

Opens a remote COPC URL using bounded HTTP range requests.
