Expand description

Extension trait for iterators of Hex

Required Methods§

Method which takes an iterator and finds the mean (average) value.

This method will return Hex::ZERO on an empty iterator

let mean = Hex::ZERO.range(10).average();
assert_eq!(mean, Hex::ZERO);

Method which takes an iterator and finds the center (centroid) value.

This method will return Hex::ZERO on an empty iterator

let center = Hex::ZERO.range(10).center();
assert_eq!(center, Hex::ZERO);

Method which takes an iterator and finds the bounds containing all elements.

This method will return (Hex::ZERO, 0) on an empty iterator

let bounds = Hex::ZERO.range(10).bounds();
assert_eq!(bounds.center, Hex::ZERO);
assert_eq!(bounds.radius, 10);
