Struct FactoryRegistry 

pub struct FactoryRegistry { /* private fields */ }

Thread-safe registry of factory contracts and their discovered children.

Call register to add factory configurations, then feed incoming events through process_event. When a creation event is detected, the child address is extracted and tracked.

Use get_all_addresses to build an EventFilter that covers all factory and child addresses.

Implementations

impl FactoryRegistry

pub fn new() -> Self

Create a new, empty factory registry.

pub fn register(&self, config: FactoryConfig)

Register a factory contract configuration.

After registration, any DecodedEvent from this factory with the matching topic0 will be checked for child address extraction.

pub fn process_event(&self, event: &DecodedEvent) -> Option<DiscoveredChild>

Process an incoming event, checking if it is a factory creation event.

Returns Some(DiscoveredChild) if the event matched a registered factory and a new child address was extracted. Returns None if:

• The event is not from a registered factory.
• The event topic0 does not match a creation event.
• The child address was already discovered (dedup).
• The child address field could not be found in fields_json.

pub fn get_all_addresses(&self) -> Vec<String>

Get all tracked addresses (factories + discovered children).

Useful for building an EventFilter that covers all contracts the indexer should watch.

pub fn children_of(&self, factory_address: &str) -> Vec<DiscoveredChild>

Get all children discovered from a specific factory.

Returns an empty vec if the factory has no children or is not registered.

pub fn snapshot(&self) -> FactorySnapshot

Create a serializable snapshot of the current registry state.

Use this to persist discovered children across restarts.

pub fn restore(&self, snapshot: FactorySnapshot)

Restore the registry from a previously saved snapshot.

This re-registers all factory configs and re-populates the children sets. Any existing state is merged (not replaced).

pub fn factory_count(&self) -> usize

Returns the number of registered factories.

pub fn child_count(&self) -> usize

Returns the total number of discovered children across all factories.
