Trait Child 

pub trait Child:
    Identifiable
    + SignalReceiver
    + Statusable
    + Send
    + Sync {
    // Provided method
    fn set_context(&mut self, _ctx: Box<dyn ChildContext>) { ... }
}

A child entity managed by a Component.

All entities held inside a Component must implement this trait. This ensures they can:

• Be identified (Identifiable)
• Respond to signals (SignalReceiver)
• Report status (Statusable)

Object Safety

This trait is object-safe, allowing Box<dyn Child>.

Signal Propagation

When a Component receives a signal, it MUST forward it to all children:

fn on_signal(&mut self, signal: &Signal) -> SignalResponse {
    // Handle self first
    // ...

    // Forward to ALL children
    for child in &mut self.children {
        child.on_signal(signal);
    }
}

Type Parameter Alternative

For stronger typing, Components can use:

struct MyComponent<C: Child> {
    children: Vec<C>,
}

Provided Methods

fn set_context(&mut self, _ctx: Box<dyn ChildContext>)

Inject a ChildContext so the child can use orcs.* functions at runtime (RPC, exec, spawn, file tools, etc.).

The default implementation is a no-op — override when the child actually needs context (e.g. LuaChild).
