Enum HatState

pub enum HatState {
    Centered = 0,
    Up = 1,
    Right = 2,
    Down = 4,
    Left = 8,
    RightUp = 3,
    RightDown = 6,
    LeftUp = 9,
    LeftDown = 12,
}

This is represented in SDL2 as a bitfield but obviously not all combinations make sense: 5 for instance would mean up and down at the same time… To simplify things I turn it into an enum which is how the SDL2 docs present it anyway (using macros).

Variants

Centered = 0

Up = 1

Right = 2

Down = 4

Left = 8

RightUp = 3

RightDown = 6

LeftUp = 9

LeftDown = 12

Implementations

pub fn to_raw(self) -> u8

Trait Implementations

impl Clone for HatState

fn clone(&self) -> HatState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HatState

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

Formats the value using the given formatter.

impl Hash for HatState

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 HatState

fn eq(&self, other: &HatState) -> 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.
