Struct laz::laszip::parallel::ParLasZipDecompressor

pub struct ParLasZipDecompressor<R> { /* private fields */ }

Laszip decompressor, that can decompress data using multiple threads

Supports both fixed-size and variable-size chunks.

Implementations

impl<R: Read + Seek> ParLasZipDecompressor<R>

pub fn new(source: R, vlr: LazVlr) -> Result<Self>

Creates a new decompressor

Fails if no chunk table could be found.

The created decompressor will decompress all data

pub fn selective( source: R, vlr: LazVlr, selection: DecompressionSelection ) -> Result<Self>

Creates a new decompressor, that will only decompress fields that are selected by the selection.

Fails if not chunk table could be found

pub fn decompress_many(&mut self, out: &mut [u8]) -> Result<()>

Decompresses many points using multiple threads

For this function to actually use multiple threads, the points buffer shall hold more points that the vlr’s chunk_size.

pub fn seek(&mut self, index: u64) -> Result<()>

Seeks to the position of the point at the given index

pub fn into_inner(self) -> R

pub fn get_mut(&mut self) -> &mut R

pub fn get(&self) -> &R
