Trait OrExit

pub trait OrExit<R, S>
where
    S: AsRef<str>,
{
    // Required method
    fn or_exit(self, message: S, code: i32) -> R;
}

Types implementing the OrExit provide the or_exit function that can be used to exit a program when a computation was not successful.

The goal of this thread is to provide a function similar to unwrap() without a panic.

Required Methods

fn or_exit(self, message: S, code: i32) -> R

Exit the program with the given message and status code if the computation is not successful. Otherwise, unwrap the value and return it.

Implementations on Foreign Types

where S: AsRef<str>, E: Display,
