Function aom_decode::chroma::yuv_420

pub fn yuv_420<'a, T: Copy + 'a, YRowsIter: 'a, URowsIter: 'a, VRowsIter: 'a>(
    y: YRowsIter, 
    u: URowsIter, 
    v: VRowsIter
) -> impl Iterator<Item = YUV<T>> + 'a where
    YRowsIter: Iterator<Item = &'a [T]>,
    URowsIter: Iterator<Item = &'a [T]>,
    VRowsIter: Iterator<Item = &'a [T]>, 

Iterator that combines planes of Y, U, V into YUV pixels, where U and V have half width and half height

Uses nearest-neighbor scaling.
