pub struct RunBuilder<'a, N, F = CliFrontend>
where
    N: Node,
    F: Frontend,
{ /* private fields */ }

A builder that runs the narrative when it is dropped

Implementations

impl<'a, N, F> RunBuilder<'a, N, F>

where N: Node, F: Frontend,

pub fn command<C, G>(self, names: C, command: G) -> Self

where C: CommandNames, G: Fn(&mut Runtime<'_, N, F>) -> Interrupt<N> + 'static,

Add a global command to the Runtime

Global commands can always be entered by the user.

Some examples of global commands might be:

• save
• inventory / inv
• look around
