Module distributed 

Distributed region encoding, symbol distribution, and recovery.

This module implements encoding of distributed region state into RaptorQ symbols, their distribution to replicas, and recovery of region state from collected symbols. It builds on the state model from crate::record::distributed_region and the symbol types from crate::types::symbol.

Modules

• snapshot: Serializable region state snapshots
• encoding: RaptorQ encoding pipeline for snapshots
• assignment: Symbol-to-replica assignment strategies
• consistent_hash: Deterministic consistent hash ring
• distribution: Quorum-based symbol distribution
• recovery: Region recovery protocol
• bridge: Local-to-distributed region bridge
