Trait embedded_graphics_framebuf::backends::DMACapableFrameBufferBackend

pub unsafe trait DMACapableFrameBufferBackend: FrameBufferBackend {
    fn data_ptr(&self) -> *const Self::Color;
}

Backends implementing this Trait can be used for DMA.

Safety

The same restrictions as for embedded_dma::ReadBuffer apply.

Required Methods

fn data_ptr(&self) -> *const Self::Color

Implementations on Foreign Types

impl<'a, C: PixelColor, const N: usize> DMACapableFrameBufferBackend for &'a mut [C; N]

Safety:

The implementation of the trait for all lifetimes 'a is safe. However, this doesn’t mean that the use of it is safe for all lifetimes. The requirements specified in embedded_dma::ReadBuffer::read_buffer remain.

fn data_ptr(&self) -> *const C
