Expand description

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

Pseudocode:
¬ a.ends_with(b)

  • If true, return ().

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

§Examples

use assertables::*;

// String ends with substring?
let whole: &str = "alfa";
let part: &str = "al";
assert_not_ends_with!(sequence, x);

// Vector ends with element?
let whole = vec![1, 2, 3];
let part = [1];
assert_not_ends_with!(sequence, x);

// This will panic
let whole = "alfa";
let part = "fa";
assert_not_ends_with!(sequence, x);
// assertion failed: `assert_not_ends_with!(sequence, x)`
// https://docs.rs/assertables/9.2.0/assertables/macro.assert_not_ends_with.html
//  whole label: `whole`,
//  whole debug: `\"alfa\"`,
//   part label: `part`,
//   part debug: `\"fa\"`
