Macro assert_not_contains

macro_rules! assert_not_contains {
    ($container:expr, $containee:expr $(,)?) => { ... };
    ($container:expr, $containee:expr, $($message:tt)+) => { ... };
}

Assert an expression (such as a string) does not contain an expression (such as a substring).

Pseudocode:
¬ a.contains(b)

• If true, return ().

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

Examples

use assertables::*;

// String contains substring?
let a = "alfa";
let b = "zz";
assert_not_contains!(a, b);

// Range contains value?
let a = 1..3;
let b = 4;
assert_not_contains!(a, &b);

// Vector contains element?
let a = vec![1, 2, 3];
let b = 4;
assert_not_contains!(a, &b);

// This will panic
let a = "alfa";
let b = "lf";
assert_not_contains!(a, b);
// assertion failed: `assert_not_contains!(container, containee)`
// https://docs.rs/assertables/9.5.3/assertables/macro.assert_not_contains.html
//  container label: `a`,
//  container debug: `\"alfa\"`,
//  containee label: `b`,
//  containee debug: `\"lf\"`
