Enum Dir 

#[repr(u8)]
pub enum Dir {
    Up = 0,
    RightUp = 1,
    RightDown = 2,
    Down = 3,
    LeftDown = 4,
    LeftUp = 5,
}

One of the six lattice directions of the flat-top hex grid, ordered clockwise starting at the top.

In axial coordinates the deltas are:

direction	delta	pixel delta (size = circumradius)
Dir::Up	(0, -1)	(0, -√3·size)
Dir::RightUp	(1, -1)	(1.5·size, -√3/2·size)
Dir::RightDown	(1, 0)	(1.5·size, +√3/2·size)
Dir::Down	(0, +1)	(0, +√3·size)
Dir::LeftDown	(-1, +1)	(-1.5·size, +√3/2·size)
Dir::LeftUp	(-1, 0)	(-1.5·size, -√3/2·size)

Variants

Up = 0

RightUp = 1

RightDown = 2

Down = 3

LeftDown = 4

LeftUp = 5

Implementations

impl Dir

pub const ALL: [Dir; 6]

All directions, clockwise. The index in this array is the bit index used by Arrows and the angle used when painting an arrow.

pub fn delta(self) -> (i32, i32)

Axial-coordinate delta of this direction.

pub fn opposite(self) -> Dir

The direction pointing the opposite way.
