Enum DisplayRotation

pub enum DisplayRotation {
    Deg0,
    Deg90,
    Deg180,
    Deg270,
}

Some Fuchsia device displays are mounted rotated. This value represents The supported rotations and can be used by views to rotate their content to display appropriately when running on the frame buffer.

Implementations

impl DisplayRotation

pub fn transform(&self, target_size: &Size2D<Coord>) -> Transform2D<Coord>

Create a transformation to accommodate the screen rotation.

pub fn inv_transform(&self, target_size: &Size2D<Coord>) -> Transform2D<Coord>

Create a transformation to undo the screen rotation.

Trait Implementations

impl Clone for DisplayRotation

fn clone(&self) -> DisplayRotation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DisplayRotation

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

Formats the value using the given formatter.

impl Default for DisplayRotation

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DisplayRotation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<DisplayRotation> for Angle<Coord>

fn from(display_rotation: DisplayRotation) -> Self

Converts to this type from the input type.

impl FromStr for DisplayRotation

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for DisplayRotation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<u32> for DisplayRotation

type Error = Error

The type returned in the event of a conversion error.

fn try_from(num: u32) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for DisplayRotation

impl Eq for DisplayRotation
