Commands + +1. **Define Command Structure** +```rust +// In src/main.rs +#[derive(Subcommand)] +enum Commands { + // ... existing commands ... + + /// New command description + NewCommand { + /// Command argument + arg: String, + /// Optional flag + #[arg(long)] + flag: bool, + }, +} +``` + +2. **Implement Command Logic** +```rust +// In src/main.rs match statement +Commands::NewCommand { arg, flag } => { + let result = call_daemon_with_fallback( + |client| Box::pin(client.new_command(arg.clone(), flag)), + || Box::pin(async { + // Fallback implementation + let system = AptOstreeSystem::new("debian/stable/x86_64").await?; + system.new_command(&arg, flag).await?; + Ok("Command completed successfully".to_string()) + }) + ).await?; + + println!("{}", result); +} +``` + +3. **Add Daemon Method** +```rust +// In src/bin/apt-ostreed.rs +#[dbus_interface(name = "org.aptostree.dev.Daemon")] +impl AptOstreeDaemon { + async fn new_command(&self, arg: String, flag: bool) -> zbus::fdo::Result { + // Implementation + Ok("Command result".to_string()) + } +} +``` + +4. **Add Client Method** +```rust +// In src/daemon_client.rs +impl DaemonClient { + pub async fn new_command(&self, arg: String, flag: bool) -> Result> { + let reply: String = self.proxy.call("new_command", &(arg, flag)).await?; + Ok(reply) + } +} +``` + +### Adding New Modules + +1. **Create Module File** +```rust +// src/new_module.rs +use crate::error::{AptOstreeError, AptOstreeResult}; + +pub struct NewModule { + // Module state +} + +impl NewModule { + pub fn new() -> AptOstreeResult { + Ok(Self {}) + } + + pub async fn do_something(&self) -> AptOstreeResult<()> { + // Implementation + Ok(()) + } +} +``` + +2. **Add to lib.rs** +```rust +// src/lib.rs +pub mod new_module; +``` + +3. **Add Tests** +```rust +// src/new_module.rs +#[cfg(test)] +mod tests { + use super::*; + + #[tokio::test] + async fn test_new_module() { + let module = NewModule::new().unwrap(); + assert!(module.do_something().await.is_ok()); + } +} +``` + +## Testing + +### Unit Tests + +```bash +# Run all tests +cargo test + +# Run specific test +cargo test test_name + +# Run tests with
