Crate soar_db 

Database layer for the soar package manager.

This crate provides database management for soar, including:

• Connection management: Separate connections for core and metadata databases
• Models: Diesel ORM models for all database tables
• Repositories: Type-safe CRUD operations using the repository pattern
• Migrations: Automatic schema migrations using diesel_migrations

Database Architecture

Soar uses two types of SQLite databases:

• Core database (core.db): Tracks installed packages
• Metadata databases (one per repository): Contains package metadata

Example

use soar_db::connection::DatabaseManager;
use soar_db::repository::core::CoreRepository;
use soar_db::repository::metadata::MetadataRepository;

// Create database manager
let mut manager = DatabaseManager::new("/path/to/db")?;

// Add repository metadata
manager.add_metadata_db("pkgforge", "/path/to/pkgforge.db")?;

// Query installed packages (DbConnection derefs to SqliteConnection)
let installed = CoreRepository::list_all(manager.core())?;

// Search for packages
if let Some(metadata) = manager.metadata("pkgforge") {
    let packages = MetadataRepository::search(metadata, "firefox")?;
}
