Struct SpatialTensorChunk 

pub struct SpatialTensorChunk { /* private fields */ }

One contiguous index range within a SpatialTensor chunk iteration.

Implementations

impl SpatialTensorChunk

pub fn range(&self) -> Range<usize>

Returns the half-open index range [start, end) for this chunk.

pub fn len(&self) -> usize

Returns the number of points in this chunk.

pub fn is_empty(&self) -> bool

Returns whether this chunk is empty.

pub fn field_f32<'a>( &self, cloud: &'a PointCloud, name: &str, ) -> Result<&'a [f32], SpatialError>

Returns a slice of an f32 field column for this chunk.

pub fn field_buffer<'a>( &self, cloud: &'a PointCloud, name: &str, ) -> Result<SpatialTensorFieldChunk<'a>, SpatialError>

Returns the underlying buffer slice for any field dtype in this chunk.

impl SpatialTensorChunk

pub fn pack_xyz( &self, cloud: &PointCloud, ) -> Result<AoSoAXyzChunk, SpatialError>

Packs this chunk into an owned interleaved XYZ buffer.

pub fn pack_xyz_intensity( &self, cloud: &PointCloud, ) -> Result<AoSoAAttributeChunk, SpatialError>

Packs interleaved XYZ and intensity records.

pub fn pack_xyz_normals( &self, cloud: &PointCloud, ) -> Result<AoSoAAttributeChunk, SpatialError>

Packs interleaved XYZ and normal records.

pub fn pack_xyz_intensity_normals( &self, cloud: &PointCloud, ) -> Result<AoSoAAttributeChunk, SpatialError>

Packs interleaved XYZ, intensity, and normal records.

pub fn pack_xyz_into( &self, cloud: &PointCloud, out: &mut Vec<f32>, ) -> Result<usize, SpatialError>

Packs this chunk into out, returning the number of points written.

out is cleared first and resized to 3 * chunk.len() floats.

Trait Implementations

impl Clone for SpatialTensorChunk

fn clone(&self) -> SpatialTensorChunk

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SpatialTensorChunk

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for SpatialTensorChunk

fn eq(&self, other: &SpatialTensorChunk) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
