Macro assert_is_empty 

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

Assert an expression (such as a string or array) is empty.

Pseudocode:
a.is_empty()

• If true, return ().

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

Examples

use assertables::*;

let a = "";
assert_is_empty!(a);

// This will panic
let a = "alfa";
assert_is_empty!(a);
// assertion failed: `assert_is_empty!(a)`
// https://docs.rs/assertables/…/assertables/macro.assert_is_empty.html
//  label: `a`,
//  debug: `\"alfa\"`
