}

Test the value and return a result object containing either the inner value or an error object that, when displayed, will provide the specified error message.

Required methods

fn expect_result_nb_(self, msg: &str) -> Result<T, ExpectationFailed>

Return a result object with a non-boxed Error object.

fn expect_result_(self, msg: &str) -> Result<T, Box<dyn Error>>

Return a result object that may be tested using the ? operator.

fn expect_result_nb<F>(self, f: F) -> Result<T, ExpectationFailed> where
    F: FnOnce() -> String, 

Return a result object with a non-boxed Error object. Invoke the specified function to obtain the error message.

fn expect_result<F>(self, f: F) -> Result<T, Box<dyn Error>> where
    F: FnOnce() -> String, 

Return a result object that may be tested using the ? operator. Invoke the specified function to obtain the error message.
