Macro assertables::assert_not_ends_with

macro_rules! assert_not_ends_with {
    ($a:expr, $b:expr $(,)?) => { ... };
    ($a:expr, $b:expr, $($message:tt)+) => { ... };
}

Assert an expression (such as a string) does not end with 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

// Return Ok
let a = "foogoo";
let b = "foo";
assert_not_ends_with!(a, b);
//-> ()

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