Module embedded_graphics::pixelcolor [−][src]
Pixel color trait
Driver implementers should implement PixelColor
for the struct used to store pixels for the
target display. An example can be found in
the simulator. A simpler example looks like this:
use embedded_graphics::drawable::Pixel; use embedded_graphics::unsignedcoord::UnsignedCoord; use embedded_graphics::pixelcolor::PixelColor; // `Copy` and `Clone` are bounds on `PixelColor` and are required. // `PartialEq` is for the `assert_eq!()` later in this example. // `Debug` is for convenience :) #[derive(Copy, Clone, PartialEq, Debug)] struct CustomPixelColor { pub value: u16, } impl CustomPixelColor { fn new(color: u16) -> Self { CustomPixelColor { value: color } } } impl PixelColor for CustomPixelColor {} // `From<u8>` is a bound on `PixelColor` so must be implemented for your pixel colour type impl From<u8> for CustomPixelColor { fn from(other: u8) -> Self { CustomPixelColor { value: other as u16, } } } fn main() { let colour = CustomPixelColor::new(127u16); assert_eq!(colour.value, 127u16); }
