Module export 

Phase 5: Structured data export (JSON, Parquet, Avro).

Reads a PCAP file, applies optional filters, and writes each packet as a typed record to the requested format.

Pipeline (7.3 channel-based)

1. A producer thread streams packets from the PCAP file, applies structured + BPF filters, and sends PacketRecords through a bounded std::sync::mpsc::sync_channel.
2. The main thread receives records and writes them to a format-specific PacketSink (JSON, Parquet, or Avro).

Decoupling I/O (producer) from serialisation (consumer) lets both stages run concurrently, improving throughput for CPU-bound formats.

Modules

Functions

export_file
