Enum ScreenRotation

#[repr(u16)]
pub enum ScreenRotation {
    Normal = 0,
    ClockWise = 90,
    UpsideDown = 180,
    CounterClockWise = 270,
}

Possible orientations of the display. Note that this should only affect the visual representation of the screen; draw operations still act as if the screen rotation is 0. Only used by some Octo games.

Variants

Normal = 0

Normal landscape screen display, used by 99.9999% of CHIP-8 games

ClockWise = 90

Portrait screen display, ie. a normal screen rotated 90 degrees clockwise

UpsideDown = 180

Upside down landscape screen display

CounterClockWise = 270

Portrait screen display, ie. a normal screen rotated 90 degrees counter-clockwise

Trait Implementations

impl Debug for ScreenRotation

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

Formats the value using the given formatter.

impl Default for ScreenRotation

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ScreenRotation

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ScreenRotation

fn eq(&self, other: &ScreenRotation) -> 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 ScreenRotation

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
