mod.rs

Overview

This file serves as a central module aggregator and re-exporter for a set of related submodules concerning archival data structures and database helper utilities. It organizes and exposes key components related to accounts, blocks, messages, transactions, and SQLite helper functions within the archival context of the system. By doing so, it simplifies the import paths for other parts of the application that need to interact with these modules.

Modules

The file declares the following public submodules:

account — Contains structures and logic related to archived account data.
block — Contains structures and logic related to archived blockchain blocks.
message — Contains structures and logic related to archived messages.
sqlite_helper — Provides helper functions and utilities for SQLite database operations.
transaction — Contains structures and logic related to archived transactions.

Re-exports

To facilitate easier access, the file re-exports selected types from these modules at the parent module level:

Re-exported Item	Original Module	Description
`ArchAccount`	`account`	Represents an archived account entity.
`ArchBlock`	`block`	Represents an archived blockchain block.
`ArchMessage`	`message`	Represents an archived message entity.
`ArchTransaction`	`transaction`	Represents an archived transaction entity.
`FlatTransaction`	`transaction`	Represents a flattened view of a transaction.

These re-exports allow other components to import these types directly from this module instead of accessing each submodule individually.

Implementation Details and Usage

Each submodule likely encapsulates domain-specific data models and associated methods for interacting with archival data.
The sqlite_helper module provides database interaction utilities, possibly abstracting away raw SQL queries and connection handling.
The archival data structures (ArchAccount, ArchBlock, ArchMessage, ArchTransaction) are expected to map to persisted data representations useful for querying historical blockchain or ledger data.
FlatTransaction is a specialized structure that likely provides a denormalized or simplified view of transaction data for easier consumption or display.

Interactions with Other System Components

This module acts as a bridge between the archival data storage layer and higher-level business logic or API layers.
Other parts of the system that need to query, display, or manipulate historical blockchain data import these archival types and utilities.
The sqlite_helper submodule supports database operations utilized by archival modules to persist and retrieve data efficiently.
The organization promotes modularity by grouping related archival functionalities while exposing a concise API surface.
