where
    F: Frame,
    T: ToFrameSliceMut<'a, F>,

ยงExamples

extern crate sample;

fn main() {
    let foo = &mut [0.0, 0.5, 0.0, -0.5][..];
    let bar = sample::slice::to_frame_slice_mut(foo);
    assert_eq!(bar, Some(&mut [[0.0, 0.5], [0.0, -0.5]][..]));

    let foo = &mut [0.0, 0.5, 0.0][..];
    let bar = sample::slice::to_frame_slice_mut(foo);
    assert_eq!(bar, None::<&mut [[f32; 2]]>);
