Struct PointBlock 

pub struct PointBlock {
    pub len: usize,
    /* private fields */
}

SoA (Structure of Arrays) storage for point cloud data.

Internally uses Vec for O(1) index-based access, with a HashMap for name-based lookups. This provides efficient iteration while maintaining backwards-compatible named access.

Fields

len: usize

Number of points

Implementations

impl PointBlock

pub fn new(schema: &Vec<(String, ValueType)>, capacity: usize) -> Self

pub fn resize(&mut self, new_len: usize)

pub fn get_column(&self, name: &str) -> Option<&Column>

Get a column by name (backwards-compatible API). For performance-critical code, prefer get_column_by_index.

pub fn get_column_mut(&mut self, name: &str) -> Option<&mut Column>

Get a mutable column by name (backwards-compatible API). For performance-critical code, prefer get_column_mut_by_index.

pub fn get_column_by_index(&self, index: usize) -> Option<&Column>

O(1) indexed access to a column.

pub fn get_column_mut_by_index(&mut self, index: usize) -> Option<&mut Column>

O(1) mutable indexed access to a column.

pub fn get_column_index(&self, name: &str) -> Option<usize>

Get the index of a column by name.

pub fn schema(&self) -> &[String]

Get the schema (field names in order).

pub fn num_columns(&self) -> usize

Number of columns.

pub fn get_columns_mut(&mut self, names: &[String]) -> Option<Vec<&mut Column>>

Optimized: Get multiple mutable columns simultaneously. Returns None if any column is missing or if names contain duplicates. This avoids O(N*M) lookup inside tight loops.

pub fn columns(&self) -> &[Column]

Access underlying columns slice (for iteration).

pub fn columns_mut(&mut self) -> &mut [Column]

Access underlying columns mutably.

pub fn xyz(&self) -> Option<(&[f32], &[f32], &[f32])>

Get XYZ coordinates as f32 slices. Returns None if any of x, y, z columns are missing or not F32.

pub fn xyzi(&self) -> Option<(&[f32], &[f32], &[f32], &[f32])>

Get XYZ + intensity as f32 slices. Returns None if any column is missing or has wrong type.

pub fn xyzrgb(&self) -> Option<(&[f32], &[f32], &[f32], &[u32])>

Get XYZ + RGB (packed as u32) slices. Returns None if any column is missing or has wrong type.

pub fn xyzir(&self) -> Option<(&[f32], &[f32], &[f32], &[f32], &[u16])>

Get XYZ + intensity + ring (common LiDAR format). Returns None if any column is missing or has wrong type.

• intensity: F32
• ring: U16

pub fn xyzirt(&self) -> Option<(&[f32], &[f32], &[f32], &[f32], &[u16], &[f64])>

Get XYZ + intensity + ring + timestamp (full LiDAR format). Returns None if any column is missing or has wrong type.

• intensity: F32
• ring: U16
• timestamp: F64

pub fn xyzirt_id( &self, ) -> Option<(&[f32], &[f32], &[f32], &[f32], &[u16], &[f64], &[u32])>

Get XYZIRT + id (LiDAR format with point ID/label). Returns None if any column is missing or has wrong type.

• intensity: F32
• ring: U16
• timestamp: F64
• id: U32
