Display and callback system for PraisonAI
This module provides display functions and callback registration matching the Python SDK's
main.py display system.
# Features
* Display functions for various output types (interaction, tool calls, errors, etc.)
* Callback registration for custom display handling
* Approval callback for dangerous operations
* Color palette for consistent UI
# Example
```rust,ignore theme={"theme":{"light":"vitesse-light","dark":"vitesse-dark"}}
use praisonai::display::{register_display_callback, display_interaction, DisplayType};
// Register a custom callback
register_display_callback(DisplayType::Interaction, |event| {
println!("Agent: {} said: {}", event.agent_name, event.content);
});
// Display an interaction
display_interaction("assistant", "Hello!", None);
```
