Crate signet_cold_mdbx 

MDBX table definitions and backend for cold storage.

This crate provides table definitions for storing historical blockchain data in MDBX. It defines 9 tables:

Primary Data Tables

• ColdHeaders: Block headers indexed by block number.
• ColdTransactions: Transactions indexed by (block number, tx index).
• ColdTxSenders: Transaction senders indexed by (block number, tx index).
• ColdReceipts: Receipts indexed by (block number, tx index).
• ColdSignetEvents: Signet events indexed by (block number, event index).
• ColdZenithHeaders: Zenith headers indexed by block number.

Index Tables

• ColdBlockHashIndex: Maps block hash to block number.
• ColdTxHashIndex: Maps transaction hash to (block number, tx index).

Feature Flags

• test-utils: Propagates signet-cold/test-utils for conformance testing against the MDBX backend.
