Module assertables::assert_not_match

Assert an expression (such as a regex) is not a match for an expression (such as a string).

• If true, return ().

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

Examples

use std::process::Command;
use regex::Regex;

// Return Ok
let a = Regex::new(r"foo").unwrap();
let b = "yoohoo";
assert_not_match!(a, b);
//-> ()

// Panic with error message
let result = panic::catch_unwind(|| {
let a = Regex::new(r"foo").unwrap();
let b = "foogoo";
assert_not_match!(a, b);
//-> panic!
});
assert!(result.is_err());
let actual = result.unwrap_err().downcast::<String>().unwrap().to_string();
let expect = concat!(
    "assertion failed: `assert_not_match!(matcher, matchee)`\n",
    " matcher label: `a`,\n",
    " matcher debug: `Regex(\"foo\")`,\n",
    " matchee label: `b`,\n",
    " matchee debug: `\"foogoo\"`"
);
assert_eq!(actual, expect);
