Implementations

impl GenericPointReader

pub fn open_file<P: AsRef<Path>>(path: P) -> Result<Self>

pub fn point_count(&self) -> Option<usize>

Returns the total number of points in the underlying point cloud file. Returns None if the number of points is unknown (e.g. for ASCII files which don’t have header information)

Trait Implementations

impl PointReader for GenericPointReader

fn read_into<'a, 'b, B: BorrowedMutBuffer<'a>>( &mut self, point_buffer: &'b mut B, count: usize, ) -> Result<usize>

where 'a: 'b,

Read count points from this PointReader into the given point_buffer. Uses the PointLayout of the given PointBuffer for reading. If no conversion from the default PointLayout to this new layout are possible, an error is returned. On success, returns the number of points that were read. Overwrites existing data in point_buffer starting at the first point, so the length of point_buffer must be greater than or equal to count

fn get_metadata(&self) -> &dyn Metadata

Returns the Metadata of the associated PointReader

fn get_default_point_layout(&self) -> &PointLayout

Returns the default PointLayout of the associated PointReader

fn read<'a, B: OwningBuffer<'a> + MakeBufferFromLayout<'a> + 'a>( &mut self, count: usize, ) -> Result<B>

Reads at most count points from this PointReader into a new buffer of type B. The PointLayout this new buffer will be equal to self.get_default_point_layout

impl SeekToPoint for GenericPointReader

fn seek_point(&mut self, position: SeekFrom) -> Result<usize>

Seek to the point at the given position in the underlying stream.

fn point_index(&mut self) -> Result<usize>

Returns the index of the current point in the underlying stream. This is equivalent to calling seek_point(SeekFrom::Current(0)).

fn point_count(&mut self) -> Result<usize>

Returns the total number of points in the underlying stream.
