Struct Answer 

pub struct Answer(/* private fields */);

What a blocked shell is told to run next: one command, as an arglist — the same shape a message has, encoded the same way.

Implementations

impl Answer

pub fn of( command: impl Into<String>, args: impl IntoIterator<Item = impl Into<String>>, ) -> Self

A command and the arguments it is given. The command word stands apart because a command of no words is not one.

pub fn status(code: u8) -> Self

A status for the ask, leaving the frame that asked to carry on.

pub fn unknown() -> Self

A word this rig has no answer for: 127, bash’s own “command not found”.

pub fn returning(code: u8) -> Self

return code in the frame that asked, so the function holding the call site returns — where status only gives the ask a status to test.
