Sharenet

A Rust backend for performing CRUD operations on various struct types (e.g., products, users) that uses a clean architecture with configurable storage and interface layers.

Features

• Clean architecture with separate domain, application, and infrastructure layers
• Multiple interface options:
  • HTTP REST API
  • Command Line Interface (CLI)
  • Text User Interface (TUI)
• Configurable storage backends:
  • In-memory storage
  • PostgreSQL database
• Generic implementations for easy extension
• Static dispatch with generic traits
• Axum-based HTTP API
• Clap-based CLI
• Ratatui-based TUI

cargo run --bin sharenet-cli-memory product list

CLI with PostgreSQL

cargo run --bin sharenet-cli-postgres user create --username john --email john@example.com

TUI with in-memory storage

cargo run --bin sharenet-tui-memory

TUI with PostgreSQL

Database Setup

Using SQLx CLI

1. Install SQLx CLI:

cargo install sqlx-cli

2. Create the database:

sqlx database create
