Struct PointKey 

pub struct PointKey { /* private fields */ }

The identity of a Point: the exact bit patterns of its coordinates.

This is the only way points are compared for identity anywhere in the crate. -0.0 is normalized to 0.0 first, so the two zeroes are one point; every other value keys on itself and nothing else. Ordering is by bit pattern — meaningless geometrically, but total and stable, which is what a BTreeMap needs to keep iteration reproducible.

Implementations

impl PointKey

pub const fn new(x: f64, y: f64) -> Self

The key for the coordinate pair (x, y).

pub const fn bits(self) -> (u64, u64)

The raw (x, y) bit patterns.
