Trait Termination 

pub trait Termination {
    // Required method
    fn report(self) -> i32;
}

A trait for implementing arbitrary return types in the main function.

The c-main function only supports to return integers as return type. So, every type implementing the Termination trait has to be converted to an integer.

The default implementations are returning 0 to indicate a successful execution. In case of a failure, 1 is returned.

Required Methods

fn report(self) -> i32

Is called to get the representation of the value as status code. This status code is returned to the operating system.
