with a message and the values of the expressions with their debug representations.
Examples
use std::io::Read;
let mut a = "a".as_bytes();
let mut b = "b".as_bytes();
assert_read_to_string_gt!(b, a);
//-> ()
use std::io::Read;
let mut a = "a".as_bytes();
let mut b = "b".as_bytes();
assert_read_to_string_gt!(a, b);
//-> panic!
// assertion failed: `assert_read_to_string_gt!(left, right)`
// left: `\"a\"`,
// right: `\"b\"`
This macro has a second form where a custom message can be provided.
