Enum Outcome 

pub enum Outcome<T> {
    Parsed(T),
    Exit(Exit),
}

The two things dispatching a CLI inside another runtime can do.

Variants

Parsed(T)

The command line parsed and the host can run it.

Exit(Exit)

The host should print a response and return its status without running the command.

Implementations

impl<T> Outcome<T>

pub fn parsed(self) -> Option<T>

The parsed value, if the command line was an invocation rather than a response.

pub fn exit(&self) -> Option<&Exit>

The response an embedded host should return, if parsing did not produce a value.

pub fn map<U>(self, f: impl FnOnce(T) -> U) -> Outcome<U>

The same outcome over a converted value, for a host that finalizes what it parsed.
