Pretty Print an item to a string
use debug2::pprint;
let x: Vec<Option<&[i32]>> = vec![Some(&[1; 20]), None, None, Some(&[1, 2, 3])];
assert_eq!(
pprint(x),
"\
[
Some([1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1]),

Note that while this takes a T
, you can also pass a reference due to the
impl<T: Debug> Debug for
&T`
Panics
This will panic if <T as Debug>::fmt
returns an error
