Struct PurgeCommandController 

pub struct PurgeCommandController { /* private fields */ }

Presentation layer controller for purge command workflow

Coordinates user interaction, progress reporting, and input validation before delegating to the application layer PurgeCommandHandler.

Responsibilities

• Validate user input (environment name format)
• Show progress updates to the user
• Handle confirmation prompts (unless –force is provided)
• Format success/error messages for display
• Delegate business logic to application layer

Architecture

This controller sits in the presentation layer and handles all user-facing concerns. It delegates actual business logic to the application layer’s PurgeCommandHandler, maintaining clear separation of concerns.

Implementations

impl PurgeCommandController

pub fn new( handler: PurgeCommandHandler, user_output: Arc<ReentrantMutex<RefCell<UserOutput>>>, ) -> Self

Create a new purge command controller

Creates a PurgeCommandController with the application handler. This follows the single container architecture pattern.

pub async fn execute( &mut self, environment_name: &str, force: bool, output_format: OutputFormat, ) -> Result<(), PurgeSubcommandError>

Execute the complete purge workflow

Orchestrates all steps of the purge command:

1. Validate environment name
2. Confirm operation (unless –force is provided)
3. Purge local data
4. Complete with success message

Arguments

• environment_name - The name of the environment to purge
• force - Skip confirmation prompt if true
• output_format - Output format (text or JSON)

Errors

Returns an error if:

• Environment name is invalid (format validation fails)
• Environment cannot be loaded from repository
• User cancels operation at confirmation prompt
• Purge operation fails
• Progress reporting encounters a poisoned mutex

Returns

Returns Ok(()) on success, or a PurgeSubcommandError if any step fails.
