Function round_up

pub fn round_up<T: Into<U>, U: Copy + PrimInt>(
    offset: U,
    block_size: T,
) -> Option<U>

Round offset up to next multiple of block_size. This function will fail if rounding up leads to an integer overflow.

(Note that unstable rust is currently adding the same function {integer}::checked_next_multiple_of() behind the “int_roundings” feature.)
