Struct Index2DBuilder 

pub struct Index2DBuilder { /* private fields */ }

Builder for Index2D and, with the simd feature, SimdIndex2D.

Example

use packed_spatial_index::{Index2DBuilder, Box2D};

let mut builder = Index2DBuilder::new(2);
builder.add(Box2D::new(0.0, 0.0, 1.0, 1.0));
builder.add(Box2D::new(5.0, 5.0, 6.0, 6.0));

let index = builder.finish().unwrap();
assert_eq!(index.search(Box2D::new(0.0, 0.0, 2.0, 2.0)), vec![0]);

Implementations

impl Index2DBuilder

pub fn new(count: usize) -> Self

Create a builder for exactly count items with DEFAULT_NODE_SIZE.

pub fn node_size(self, node_size: usize) -> Self

Set the maximum number of children per tree node (clamped to [2, 65535]).

pub fn sort_key(self, key: SortKey2D) -> Self

Choose the sort key (default: SortKey2D::Hilbert).

pub fn parallel(self, parallel: bool) -> Self

Allow adaptive parallel builds through rayon.

Default is false. When set to true, rayon is used only when the item count is at least the current parallel_min_items threshold.

pub fn parallel_min_items(self, min_items: usize) -> Self

Set the minimum count at which parallel(true) actually enables rayon.

pub fn add(&mut self, item: Box2D)

Add one indexed box.

pub fn finish(self) -> Result<Index2D, BuildError>

Pack the tree and return the finished index.

pub fn finish_simd(self) -> Result<SimdIndex2D, BuildError>

Pack the tree into the SIMD-accelerated SoA index.

Example

use packed_spatial_index::{Index2DBuilder, Box2D};

let mut builder = Index2DBuilder::new(1);
builder.add(Box2D::new(0.0, 0.0, 1.0, 1.0));

let index = builder.finish_simd().unwrap();
assert_eq!(index.search(Box2D::new(0.5, 0.5, 0.5, 0.5)), vec![0]);
