The interact_prompt crate provides helpers for registering data to be examined. Currently, data must be owned, so if it is shared by threads running in the background in parallel to the prompt, it needs to be provided using Arc<_>. If the data is expeced to be shared and mutable by the Interact prompt, then it should be wrapped in Arc<Mutex<_>>.

For example:

use interact_prompt::{SendRegistry};

fn register_global_mutable_data(global_state: Arc<Mutex<MyData>>) {
    SendRegistry::insert("global", Box::new(global_state));
}

fn register_global_readable_data(readonly: Arc<MyData>) {
    SendRegistry::insert("readonly", Box::new(readonly));
}
