Enum Exit 

pub enum Exit {
    Ended {
        code: i32,
    },
    Signalled,
    Unknown {
        why: Unseen,
    },
}

How a child process stopped.

Three answers rather than one number: one integer cannot tell “it returned minus one”, “a signal stopped it” and “this city never found out” apart, and a program that really does return minus one is ordinary.

Variants

Ended

It ran to the end and returned this code.

Fields

code: i32

Signalled

A signal stopped it, so there is no code to return. This is what halt leaves behind on a Unix host.

Unknown

This city cannot say how it stopped.

Fields

why: Unseen
