Trait exr::image::read::specific_channels::RecursivePixelReader

pub trait RecursivePixelReader {
    type RecursiveChannelDescriptions;
    type RecursivePixel: Copy + Default + 'static;

    fn get_descriptions(&self) -> Self::RecursiveChannelDescriptions;
    fn read_pixels<'s, FullPixel>(
        &self, 
        bytes: &'s [u8], 
        pixels: &mut [FullPixel], 
        get_pixel: impl Fn(&mut FullPixel) -> &mut Self::RecursivePixel
    );
}

A reader containing sub-readers for reading the pixel content of an image.

Required Associated Types

type RecursiveChannelDescriptions

The channel descriptions from the image. Will be converted to a tuple before being stored in SpecificChannels<_, ChannelDescriptions>.

type RecursivePixel: Copy + Default + 'static

The pixel type. Will be converted to a tuple at the end of the process.

Required Methods

fn get_descriptions(&self) -> Self::RecursiveChannelDescriptions

Returns the channel descriptions based on the channels in the file.

fn read_pixels<'s, FullPixel>(
    &self,
    bytes: &'s [u8],
    pixels: &mut [FullPixel],
    get_pixel: impl Fn(&mut FullPixel) -> &mut Self::RecursivePixel
)

Read the line of pixels.
