}Expand description
Assert a read_to_string() value is 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 = "a".as_bytes();
assert_read_to_string_eq!(a, b);
//-> ()
use std::io::Read;
let mut a = "a".as_bytes();
let mut b = "b".as_bytes();
assert_read_to_string_eq!(a, b);
//-> panic!
// assertion failed: `assert_read_to_string_eq!(left, right)`
// left: `\"a\"`,
// right: `\"b`"This macro has a second form where a custom message can be provided.
