Macro assert_success_false

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

Assert a failure method is true.

Pseudocode:
a.success() = false

• If true, return true.

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

Examples

use assertables::*;

#[derive(Debug)]
struct A;
impl A { fn success(&self) -> bool { false }}
let a = A{};
assert_success_false!(a);

// This will panic
#[derive(Debug)]
struct A;
impl A { fn success(&self) -> bool { true }}
let a = A{};
assert_success_false!(a);
// assertion failed: `assert_success_false!(a)`
// https://docs.rs/assertables/…/assertables/macro.assert_success_false.html
//  a label: `a`,
//  a debug: `A`
