Trait Loader 

pub trait Loader:
    Debug
    + Send
    + Sync {
    // Required methods
    fn preload(
        &self,
        size: Size,
        dpi: f32,
    ) -> Result<(Vec<u8>, Size2D<u32, Pixel>), Error>;
    fn load(

        driver: &Driver,

}

Required Methods

fn preload( &self, size: Size, dpi: f32, ) -> Result<(Vec<u8>, Size2D<u32, Pixel>), Error>

The preload function does most of the work, loading the image into a byte buffer of a given width and height

fn load( &self, driver: &Driver, data: (Vec<u8>, Size2D<u32, Pixel>), resize: bool, ) -> Result<(Region, Size), Error>

The load function simply consumes the byte buffer and loads it into the atlas.
