Struct Bounds 

pub struct Bounds {
    pub min: [f64; 2],
    pub max: [f64; 2],
}

An axis-aligned bounding box in the plane.

Mirrors the minimum bounding rectangle stored at every node of a Boost rtree.

Fields

min: [f64; 2]

Lower corner [x_min, y_min].

max: [f64; 2]

Upper corner [x_max, y_max].

Implementations

impl Bounds

pub const fn new(min: [f64; 2], max: [f64; 2]) -> Self

A box from explicit corners.

pub const fn point(p: [f64; 2]) -> Self

A degenerate box at a single point.

pub fn area(&self) -> f64

The area (2D measure) of the box.

pub fn half_perimeter(&self) -> f64

Half the perimeter — Boost’s “margin”, used by the R* split.

pub fn union(&self, other: &Bounds) -> Bounds

The smallest box containing both self and other.

pub fn enlargement(&self, other: &Bounds) -> f64

How much self’s area would grow to also contain other — Boost’s enlargement metric for choose_next_node.

pub fn intersects(&self, other: &Bounds) -> bool

Whether the two boxes share any point (closed boxes, so touching counts).

pub fn contains(&self, other: &Bounds) -> bool

Whether self fully contains other.

pub fn min_distance_to(&self, p: [f64; 2]) -> f64

The minimum distance from a query point to this box (0 inside). Used by nearest-neighbour pruning.

pub fn comparable_min_distance_to(&self, p: [f64; 2]) -> f64

The SQUARED minimum distance from a query point to this box — same ordering as min_distance_to without the square root, for hot comparison paths. The analogue of boost::geometry::comparable_distance.

pub fn center(&self) -> [f64; 2]

The centroid, used by the STR bulk-load sort.
