This project is a simple CRUD (Create, Read, Update, Delete) API implemented in Rust using the Actix Web framework and the Diesel ORM for interacting with a PostgreSQL database. It provides basic functionalities to manage samples data, including creating, retrieving, updating, and deleting sample records.

• Rust (https://www.rust-lang.org/tools/install)
• Docker (https://www.docker.com/get-started)

1. Install Diesel CLI:

cargo install diesel_cli --no-default-features --features "postgres"

2. Set up the database:

• Start the PostgreSQL database using Docker:

docker-compose up -d

• Create the database schema:

diesel setup

3. Set environment variables:

• Create a .env file in the root directory and add the following content with your desired database credentials:

DATABASE_URL=postgres:https://your-db-user:your-db-password@localhost/sampledb

• Build and run the API using Cargo:

cargo run

• Refer the postman collection json in the root directory for all the details
