Struct CopcStreamingReader 

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

Async streaming COPC reader.

open() reads the LAS header, VLRs, and root hierarchy page. Deeper hierarchy pages and point chunks are loaded on demand.

Implementations

impl<S: ByteSource> CopcStreamingReader<S>

pub async fn open(source: S) -> Result<Self, CopcError>

Open a COPC file.

pub fn header(&self) -> &CopcHeader

The parsed COPC file header.

pub fn copc_info(&self) -> &CopcInfo

Shortcut for header().copc_info().

pub fn evlr_offset(&self) -> u64

File offset where EVLRs start.

pub fn evlr_count(&self) -> u32

Number of EVLRs in the file.

pub fn source(&self) -> &S

The underlying byte source.

pub fn get(&self, key: &VoxelKey) -> Option<&HierarchyEntry>

Look up a hierarchy entry by voxel key.

pub fn entries(&self) -> impl Iterator<Item = (&VoxelKey, &HierarchyEntry)>

Iterate all loaded hierarchy entries.

pub fn node_count(&self) -> usize

Number of loaded hierarchy entries.

pub fn has_pending_pages(&self) -> bool

Whether there are hierarchy pages that haven’t been loaded yet.

pub async fn load_pending_pages(&mut self) -> Result<(), CopcError>

Load the next batch of pending hierarchy pages.

pub async fn load_all_hierarchy(&mut self) -> Result<(), CopcError>

Load all remaining hierarchy pages.

pub async fn fetch_chunk( &self, key: &VoxelKey, ) -> Result<DecompressedChunk, CopcError>

Fetch and decompress a single point chunk.

pub fn read_points( &self, chunk: &DecompressedChunk, ) -> Result<Vec<Point>, CopcError>

Parse points from a decompressed chunk.
