Answer 1

You could use the macro vec! to create 2d vectors.

fn test(vec: &mut Vec<Vec<char>>){
    vec[0][0] = 'd';
    ..//
    vec[23][79] = 'd';
}

fn main() {

    let mut vec = vec![vec!['#'; 80]; 24];

    test(&mut vec);
}

Answer 2

Did you intend that all of the subarrays will have the length 2, as in this example? In that case, the type of the parameter should not be &[u8], which is a borrowed array of u8's, but rather &[[u8; 2]].
