Expand description

Assert a ::std::io::Read read_to_string() value is greater than an expression.

Pseudocode:
(reader.read_to_string(a_string) ⇒ a_string) > (expr ⇒ b_string)

  • If true, return a_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 reader = "alfa".as_bytes();
let x = String::from("aa");
assert_io_read_to_string_gt_x!(reader, x);

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