Macro o1_utils::box_array2

macro_rules! box_array2 {
    ($val:expr; $len1:expr; $len2:expr) => { ... };
}

A macro similar to vec![vec![$elem; $size1]; $size2] which returns a two-dimensional boxed array, allocated directly on the heap (via a vector, with reallocations).

    let _: Box<[[u8; 1024]; 512]> = box_array![0; 1024; 512];
