Expand description

Assert a std::fs::read_to_string() contains a pattern.

  • If true, return ().

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

§Examples

use std::io::Read;

let path = "alfa.txt";
let containee = "alfa";
assert_fs_read_to_string_contains!(&path, &containee);

let path = "alfa.txt";
let containee = "zzz";
assert_fs_read_to_string_contains!(&path, &containee);
// assertion failed: `assert_fs_read_to_string_contains!(path, containee)`
//       path label: `&path`,
//       path debug: `\"alfa.txt\"`,
//  containee label: `&containee`,
//  containee debug: `\"zzz\"`,
//      read string: `\"alfa\\n\"`
