Rust Database CRUD

Building a CRUD App

Rust database CRUD with PostgreSQL handles data operations.

Setting Up Rust and PostgreSQL

Before diving into CRUD operations, ensure you have Rust and PostgreSQL installed on your machine. Install Rust from the official Rust website and PostgreSQL from the PostgreSQL download page. Additionally, you'll need the `cargo` package manager, which comes with Rust, to manage your Rust projects.

Creating a New Rust Project

Start by creating a new Rust project using Cargo. Open your terminal and run the following command:

Adding Dependencies

Open the `Cargo.toml` file and add the following dependencies for PostgreSQL and environment management:

Connecting to PostgreSQL

To connect to the PostgreSQL database, you'll need to establish a connection using the `tokio-postgres` crate. The following example demonstrates how to connect to your database:

Creating a Table

Once connected, you can execute SQL commands to interact with your database. Here's how to create a table for storing user data:

Performing CRUD Operations

CRUD stands for Create, Read, Update, and Delete. Let's explore how each operation can be implemented using Rust and PostgreSQL.

Create Operation

To insert data into the `users` table, use the following function:

Read Operation

To read data from the `users` table, you can query and print the results as follows:

Update Operation

To update a user's data in the table, use the following function:

Delete Operation

To delete a user from the table, use the following function:
