Trait App 

pub trait App {
    // Required methods
    fn infrastructure(&self) -> &dyn Infrastructure;
    fn interface(&mut self) -> &mut dyn Interface;
}

An app: a ui tree and a swappable infra. The whole top level.

Named per suite member in the app’s own crate (KorpApp, NornirApp), because the name is the app’s; this is the shape they share. A test or a robot driver holds &mut dyn App instead of a struct private to a main.rs — which is not theoretical: korp’s struct Korp being bin-private meant 29 integration test files each redeclared their own copy and drove THAT, with one reference to the real shell in the whole directory.

Required Methods

fn infrastructure(&self) -> &dyn Infrastructure

The swappable half.

fn interface(&mut self) -> &mut dyn Interface

The ui tree’s root.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
