Struct GpuSpatialHashLayout 

pub struct GpuSpatialHashLayout<T: Clone> { /* private fields */ }

A spatial hash with an interleaved, flat-array layout for GPU upload.

Data is stored as sorted arrays of cell keys and per-item records, matching the layout expected by GPU compute shaders.

Implementations

impl<T: Clone> GpuSpatialHashLayout<T>

pub fn build(entries: &[(usize, [f32; 3], T)], cell_size: f32) -> Self

Build the GPU-friendly layout from a slice of (id, position, data).

pub fn n_items(&self) -> usize

Total number of items.

pub fn n_cells(&self) -> usize

Number of non-empty cells.

pub fn query_cell_flat(&self, cx: i32, cy: i32, cz: i32) -> Vec<(usize, &T)>

Query items in a specific cell.

pub fn to_flat_f32_buffer(&self) -> Vec<f32>

Export all items as a flat f32 buffer for GPU upload.

Format per item: [x, y, z, cell_x_f32, cell_y_f32, cell_z_f32]

pub fn cell_size(&self) -> f32

Cell size used for this layout.
