Function xdr_codec::pack_opaque_array

pub fn pack_opaque_array<Out: Write>(
    val: &[u8], 
    sz: usize, 
    out: &mut Out
) -> Result<usize>

Pack a fixed-size byte array

As size is fixed, it doesn't need to be encoded. sz is in bytes (and array elements, which are u8) If the array is too large, it is truncated; if its too small its padded with 0x00.
