Module config 

Database configuration and initialization Global database configuration and initialization

This module provides global database instance management for applications that need a singleton database connection. It includes integration with the actix-web framework for dependency injection.

Usage

Initialize the global database instance at application startup:

use switchy_database::config;
use std::sync::Arc;

// Initialize global database
config::init(Arc::new(db));

// In actix-web handlers, use ConfigDatabase for dependency injection
// It will automatically extract the global database instance

Actix-web Integration

When the api feature is enabled, ConfigDatabase implements actix-web’s FromRequest trait, allowing automatic extraction in handlers:

use actix_web::{web, HttpResponse};
use switchy_database::config::ConfigDatabase;

async fn my_handler(db: ConfigDatabase) -> HttpResponse {
    // Use db as &dyn Database via Deref
    let results = db.select("users").execute(&*db).await?;
    HttpResponse::Ok().json(results)
}

Structs
