Struct VarDisplay 

pub struct VarDisplay<'a, COLOR: ColorType + PixelColor> { /* private fields */ }

Same as Display, except that its characteristics are defined at runtime. See display for documentation as everything is the same except that default is replaced by a new method.

Implementations

impl<'a, COLOR: ColorType + PixelColor> VarDisplay<'a, COLOR>

pub fn new( width: u32, height: u32, buffer: &'a mut [u8], bwrbit: bool, ) -> Result<Self, VarDisplayError>

You must allocate the buffer by yourself, it must be large enough to contain all pixels.

Parameters are documented in Display as they are the same as the const generics there. bwrbit should be false for non tricolor displays

pub fn buffer(&self) -> &[u8]

get internal buffer to use it (to draw in epd)

pub fn set_rotation(&mut self, rotation: DisplayRotation)

Set the display rotation.

This only concerns future drawing made to it. Anything aready drawn stays as it is in the buffer.

pub fn rotation(&self) -> DisplayRotation

Get current rotation

pub fn set_pixel(&mut self, pixel: Pixel<COLOR>)

Set a specific pixel color on this display

impl<'a> VarDisplay<'a, TriColor>

Some Tricolor specifics

pub fn bw_buffer(&self) -> &[u8]

get black/white internal buffer to use it (to draw in epd)

pub fn chromatic_buffer(&self) -> &[u8]

get chromatic internal buffer to use it (to draw in epd)

Trait Implementations

impl<'a, COLOR: ColorType + PixelColor> DrawTarget for VarDisplay<'a, COLOR>

For use with embedded_grahics

type Color = COLOR

The pixel color type the targetted display supports.

type Error = Infallible

Error type to return when a drawing operation fails.

fn draw_iter<I>(&mut self, pixels: I) -> Result<(), Self::Error>

where I: IntoIterator<Item = Pixel<Self::Color>>,

Draw individual pixels to the display without a defined order.

fn fill_contiguous<I>( &mut self, area: &Rectangle, colors: I, ) -> Result<(), Self::Error>

where I: IntoIterator<Item = Self::Color>,

Fill a given area with an iterator providing a contiguous stream of pixel colors.

fn fill_solid( &mut self, area: &Rectangle, color: Self::Color, ) -> Result<(), Self::Error>

Fill a given area with a solid color.

fn clear(&mut self, color: Self::Color) -> Result<(), Self::Error>

Fill the entire display with a solid color.

impl<'a, COLOR: ColorType + PixelColor> OriginDimensions for VarDisplay<'a, COLOR>

For use with embedded_grahics

fn size(&self) -> Size

Returns the size of the bounding box.
