Trait for a microservice module

Required Methods

fn name(&self) -> &str

Unique module name

fn entity_types(&self) -> Vec<&str>

List of entity types managed by this module

fn links_config(&self) -> Result<LinksConfig>

Load links configuration

fn register_entities(&self, registry: &mut EntityRegistry)

Register entities with the entity registry

This method should register all entity descriptors for the module. Each entity descriptor provides the CRUD routes for that entity.

fn get_entity_fetcher( &self, entity_type: &str, ) -> Option<Arc<dyn EntityFetcher>>

Get an entity fetcher for a specific entity type

This allows the framework to dynamically load entities when enriching links.

Arguments

• entity_type - The type of entity (e.g., “order”, “invoice”)

Returns

An EntityFetcher implementation, or None if the entity type is not managed by this module

Provided Methods

fn version(&self) -> &str

Module version
