Simple Pastebin in Rust

In main.rs:

1. Imports: The code imports necessary modules and traits from Actix, Rusqlite, and other libraries to handle HTTP requests, database operations, and generate random tokens.

2. Data Structures: Defines a FormData struct to represent form data received from the client and an AppState struct to hold the database connection.

3. Route Handlers:

   • index: Handles GET requests to the root URL ("/") and returns the HTML content of the index page.
   • submit: Handles POST requests to "/submit" and inserts the submitted content into the database with a randomly generated token.
   • get_paste: Handles GET requests to "/paste/{token}" and retrieves the content associated with the provided token from the database.

4. Database Operations:

   • Opens or creates a SQLite database file named "pastes.db".
   • Creates a table named "pastes" if it does not exist, with columns for token (primary key) and content.

5. Actix Web Server Configuration:

   • Configures Actix web server routes for serving static files ("/style.css") and handling HTTP requests ("/", "/submit", "/paste/{token}").
   • Binds the server to the address "127.0.0.1:8080" and starts the server.

In index.html:

1. Body Content:
   • Displays the Rust mascot (Ferris) dancing as the logo.
   • Provides a heading indicating "Rust PasteBin" and a description of the application.
   • Presents a form for submitting content with a textarea and a submit button.

Running the Application:

• To run the application, execute cargo run in the terminal.
• Access the application in a web browser by navigating to http://localhost:8080.
• Enter the desired content in the textarea and click the "Submit" button to generate a URL for the paste.
• Share the generated URL with others to access the paste content.

Sum up:

This Rust project demonstrates the implementation of a simple PasteBin application using Actix for web server functionality, Rusqlite for database operations, and HTML for the user interface. It allows users to submit text content, store it in a local database, and retrieve it using a generated URL. The provided HTML file defines the structure and design of the user interface, while the Rust code handles HTTP requests, database interactions, and URL routing.

Tips:

• To run the application: cargo run
• Navigate to: http://localhost:8080
• Enter your text content in the textarea and click "Submit"
• You will be redirected to a page displaying your paste token (you can share this with anyone ~ ok, this is localhost ~ but you get the idea)
• Use ctrl + c to end the program (kill the process)
