Enum Direction 

#[repr(i8)]
pub enum Direction {
    None = 4,
    Right = 1,
    Left = -1,
    Up = 2,
    Down = -2,
}

Hinting directions.

The values are such that dir1 + dir2 == 0 when the directions are opposite.

Variants

None = 4

Undetermined direction.

Right = 1

Toward the right.

Left = -1

Toward the left.

Up = 2

Toward the top.

Down = -2

Toward the bottom.

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Direction

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Direction

fn default() -> Direction

Returns the “default value” for a type.

impl PartialEq for Direction

fn eq(&self, other: &Direction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Direction

impl Eq for Direction

impl StructuralPartialEq for Direction
