Trait WritePixels

pub trait WritePixels {
    // Required method
    async fn write_pixels(
        &mut self,
        data: &[u8],
        bit_depth: BitDepth,
        area: Rectangle,
    );

    // Provided method
    async fn flush<C>(&mut self, fb: &Framebuffer<'_, C>, top_left: Point)
       where C: PixelColor + ToBytes { ... }
}

Convenience trait to hide details of the driver type.

Once the display driver is created, only the error type depends on the HAL types used for the implementation. For the use cases where panic on error is acceptable, we can ignore the type parameters.

Required Methods

async fn write_pixels( &mut self, data: &[u8], bit_depth: BitDepth, area: Rectangle, )

See Ssd1331::write_pixels.

Provided Methods

async fn flush<C>(&mut self, fb: &Framebuffer<'_, C>, top_left: Point)

where C: PixelColor + ToBytes,

Transfers the contents of the framebuffer to the display.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
