Expand description

Assert a ::std::io::Read read_to_string() value is equal to another.

Pseudocode:
(a_reader.read_to_string(a_string) ⇒ a_string) = (b_reader.read_to_string(b_string) ⇒ b_string)

  • If true, return (a_string, b_string).

  • Otherwise, call panic! with a message and the values of the expressions with their debug representations.

§Examples

use assertables::*;
use std::io::Read;

let a = "alfa".as_bytes();
let b = "alfa".as_bytes();
assert_io_read_to_string_eq!(a, b);

// This will panic
let a = "alfa".as_bytes();
let b = "zz".as_bytes();
assert_io_read_to_string_eq!(a, b);
// assertion failed: `assert_io_read_to_string_eq!(a_reader, b_reader)`
// https://docs.rs/assertables/…/assertables/macro.assert_io_read_to_string_eq.html
//  a label: `a`,
//  a debug: `[97, 108, 102, 97]`,
//  b label: `b`,
//  b debug: `[122, 122]`,
//        a: `\"alfa\"`,
//        b: `\"zz\"`
