Macro assertables::assert_read_to_string_ne

macro_rules! assert_read_to_string_ne {
    ($left:expr, $right:expr $(,)?) => { ... };
    ($left:expr, $right:expr, $($arg:tt)+) => { ... };
}

Assert a std::io::Read read_to_string() is not equal to another.

• When true, return ().

• Otherwise, call panic! 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_ne!(a, b);
//-> ()

use std::io::Read;
let mut a = "a".as_bytes();
let mut b = "a".as_bytes();
assert_read_to_string_ne!(a, b);
//-> panic!
// assertion failed: `assert_read_to_string_ne!(left, right)`
//   left: `\"a\"`,
//  right: `\"a\"`

This macro has a second form where a custom message can be provided.
