Function libh3::k_ring_distances

pub fn k_ring_distances(origin: H3Index, radius: i32) -> Vec<(H3Index, i32)>

Get all hexagons in a k-ring around a given center, in an array of arrays ordered by distance from the origin. The order of the hexagons within each ring is undefined.

Arguments

• origin - The center of the ring.
• radius - The radis of the ring in hexagons, which is the same resolution as the origin.
