Struct ProvisionCommandController 

pub struct ProvisionCommandController { /* private fields */ }

Presentation layer controller for provision command workflow

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

Responsibilities

• Validate user input (environment name format)
• Show progress updates to the user
• 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 ProvisionCommandHandler, maintaining clear separation of concerns.

Implementations

impl ProvisionCommandController

pub fn new( repository: Arc<dyn EnvironmentRepository + Send + Sync>, clock: Arc<dyn Clock>, user_output: Arc<ReentrantMutex<RefCell<UserOutput>>>, ) -> Self

Create a new provision command controller

Creates a ProvisionCommandController with direct service injection. This follows the single container architecture pattern.

pub async fn execute( &mut self, environment_name: &str, output_format: OutputFormat, ) -> Result<Environment<Provisioned>, ProvisionSubcommandError>

Execute the complete provision workflow

Orchestrates all steps of the provision command:

1. Validate environment name
2. Load and validate environment state
3. Create command handler
4. Provision infrastructure
5. Complete with success message
6. Display provision results (connection details + DNS reminder)

Arguments

• environment_name - The name of the environment to provision
• output_format - Output format for results (Text or Json)

Errors

Returns an error if:

• Environment name is invalid (format validation fails)
• Environment cannot be loaded from repository
• Environment is not in “Created” state
• Infrastructure provisioning fails
• Progress reporting encounters a poisoned mutex

Returns

Returns Ok(Environment<Provisioned>) on success, or a ProvisionSubcommandError if any step fails.
