Macro lib::assert_result_ok

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

Assert a.is_ok() is true.

• If true, return ().

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

Examples

let a: Result<(), i8> = Result::Ok(());
assert_result_ok!(a);

let a: Result<(), i8> = Result::Err(1);
assert_result_ok!(a);
// assertion failed: `assert_result_ok!(result)`
//    result label: `a`,
//    result debug: `Err(1)`,
//  result.is_ok(): `false`
