Union Tile 

#[repr(C)]
pub union Tile {
    pub id: u16,
    pub position: [u8; 2],
}

A union representing a tile in a tilemap.

The ID should always be stored using big endian. If it is not, X and Y will be swapped, which is undesirable. Be careful!

Fields

id: u16

Identifier

position: [u8; 2]

XY position

Implementations

impl Tile

pub fn id(&self) -> u16

Safely returns the tile’s ID.

pub fn id_mut(&mut self) -> &mut u16

Safely returns a mutable reference to the tile’s ID.

Make sure any writes to this are big endian! Little endian won’t be unsound, but will swap X and Y when reading position.

pub fn position(&self) -> [u8; 2]

Safely returns the tile’s position.

pub fn position_mut(&mut self) -> &mut [u8; 2]

Safely returns a mutable reference to the tile’s position.

Trait Implementations

impl Clone for Tile

fn clone(&self) -> Tile

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Tile

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

Formats the value using the given formatter.

impl Default for Tile

fn default() -> Self

Returns the “default value” for a type.

impl Display for Tile

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

Formats the value using the given formatter.

impl PartialEq for Tile

fn eq(&self, other: &Self) -> 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 Zeroable for Tile

fn zeroed() -> Self

Calls zeroed.

impl Copy for Tile

impl Pod for Tile
