Macro assertables::assert_read_to_string_ne_other_as_result

macro_rules! assert_read_to_string_ne_other_as_result {
    ($a_reader:expr, $b_reader:expr $(,)?) => { ... };
}

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

• When true, return Result Ok(()).

• When true, return Result Err with a diagnostic message.

Examples

use std::io::Read;
let mut a = "alpha".as_bytes();
let mut b = "bravo".as_bytes();
let x = assert_read_to_string_ne_other_as_result!(a, b);
//-> Ok(())
let actual = x.unwrap();
let expect = ();
assert_eq!(actual, expect);

let mut a = "alpha".as_bytes();
let mut b = "alpha".as_bytes();
let x = assert_read_to_string_ne_other_as_result!(a, b);
//-> Err(…)
let actual = x.unwrap_err();
let expect = concat!(
    "assertion failed: `assert_read_to_string_ne_other!(left_reader, right_reader)`\n",
    "  left reader name: `a`,\n",
    " right reader name: `b`,\n",
    "  left reader size: `5`,\n",
    " right reader size: `5`,\n",
    "  left reader data: `\"alpha\"`,\n",
    " right reader data: `\"alpha\"`"
