Enum Direction 

pub enum Direction {
    Up,
    Down,
    Left,
    Right,
}

Navigation direction for focus movement.

Variants

Up

Move up (decrease y).

Down

Move down (increase y).

Left

Move left (decrease x).

Right

Move right (increase x).

Implementations

impl Direction

pub const fn opposite(self) -> Direction

Get the opposite direction.

pub const fn is_horizontal(self) -> bool

Check if this is a horizontal direction (Left or Right).

pub const fn is_vertical(self) -> bool

Check if this is a vertical direction (Up or Down).

pub const fn as_delta(self) -> (i16, i16)

Convert to a delta (dx, dy) for a single step.

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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Direction

fn deserialize<__D>( __deserializer: __D, ) -> Result<Direction, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Direction

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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 Serialize for Direction

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
