EventsRecordCodec class

Codec for encoding and decoding Substrate event records

This is the main codec that orchestrates the encoding/decoding of complete event records which include phase information, the event itself, and topics. It delegates to specialized codecs for each component.

Example:

final registry = MetadataTypeRegistry(prefixed);
final eventsRecordCodec = EventsRecordCodec(registry);

// Decode events from a block
final events = eventsRecordCodec.decode(eventBytes);
for (final event in events) {
  print('${event.event.palletName}.${event.event.eventName}: ${event.event.data}');
}
