// Example: How to add custom command handling to the Rust CLI
use anyhow::Result;
use serde_json::Value;
// This example shows how you could extend the CLI to handle custom commands
// or add client-side processing for specific commands
pub struct CustomCommandHandler {
// Custom state for command processing
}
impl CustomCommandHandler {
pub fn new() -> Self {
Self {}
}
// Example: Custom handling for "list bindings" to add client-side filtering
pub async fn handle_list_bindings(&self, args: &Value) -> Result<Value> {
// You could add client-side filtering, sorting, or formatting here
// For example, grouping bindings by exchange or destination
println!("Custom handling for list bindings command");
// In a real implementation, you might:
// 1. Call the server-side command
// 2. Post-process the results
// 3. Apply client-side filtering/formatting
// 4. Return formatted results
Ok(Value::String("Custom bindings output".to_string()))
}
// Example: Client-side command that doesn't need server interaction
pub async fn handle_local_command(&self) -> Result<Value> {
println!("This command runs entirely on the client side");
// Example: Generate shell completion scripts
// Example: Validate configuration files
// Example: Format/convert data files
Ok(Value::String("Local command result".to_string()))
}
// Example: Interactive command builder
pub async fn interactive_policy_builder(&self) -> Result<Value> {
println!("Interactive Policy Builder");
println!("This would guide users through creating policies step-by-step");
// Future enhancement: Interactive mode for complex commands
// - Prompt for required fields
// - Provide help and validation
// - Build JSON structures interactively
Ok(Value::Object(serde_json::Map::new()))

// This shows how you could extend the CLI to support:
// 1. Client-side commands that don't need server interaction
// 2. Enhanced versions of server commands with client-side processing
// 3. Interactive command builders
// 4. Custom output formatting
