Trait web_glitz::image::texture_2d_array::LevelsIndex

pub trait LevelsIndex<'a, F> {
    type Output;
    fn get(self, levels: &'a Levels<F>) -> Option<Self::Output>;
    unsafe fn get_unchecked(self, levels: &'a Levels<F>) -> Self::Output;
}

A helper trait for indexing Levels.

See Levels::get and Levels::get_unchecked.
