Struct Api

pub struct Api { /* private fields */ }

The Api struct is the main entry point for configuring and running the API server.

This struct provides methods to set up TLS, configure routes, manage CORS settings, apply rate limiting, and bind the server to a specific address and port. It is designed to simplify the process of building secure and high-performance APIs using the Actix Web framework.

Features

• TLS Support: Configure paths to certificate and key files for secure HTTPS communication.
• Rate Limiting: Set request limits to prevent abuse.
• CORS Configuration: Customize cross-origin resource sharing settings.
• Custom Routes: Define and configure API routes using the Routes builder.

Example

use rusty_api::Api;

let api = Api::new()
     .certs("certs/cert.pem", "certs/key.pem")
     .rate_limit(5, 10)
     .bind("127.0.0.1", 8443)
     .configure_cors(|| {
         rusty_api::Cors::default()
             .allow_any_origin()
             .allow_any_method()
     });
 
api.start();

pub fn bind(self, addr: &str, port: u16) -> Self

Set the address and port for the API server.

Arguments

• addr - Address to bind the server to.
• port - Port to bind the server to.

Returns

A mutable reference to the Api instance.

Example

use rusty_api::Api;

let api = Api::new().bind("127.0.0.1", 8443);
assert_eq!(api.get_bind_addr(), "127.0.0.1:8443");

pub fn configure_routes(self, routes: Routes) -> Self

Configure custom routes for the API server.

Arguments

• routes - A Routes instance containing the custom routes.

Returns

A mutable reference to the Api instance.

Example

use rusty_api::Api;
use rusty_api::Routes;

async fn example_route(_req: rusty_api::HttpRequest) -> rusty_api::HttpResponse {
  rusty_api::HttpResponse::Ok().body("Example route accessed!")
}

let routes = Routes::new()
   .add_route("/example", example_route);

let api = Api::new()
   .configure_routes(routes);

assert!(api.get_custom_routes().is_some());

pub fn configure_cors<F>(self, cors_config: F) -> Self

where F: Fn() -> Cors + Send + Sync + 'static,

Configure CORS settings.

Arguments

• cors - A closure that takes a Cors instance and returns a modified Cors instance.

Returns

A mutable reference to the Api instance.

Example

use rusty_api;

let api = rusty_api::Api::new()
    .configure_cors(|| {
        rusty_api::Cors::default()
            .allow_any_origin()
            .allow_any_method()
    });

pub fn start(self)

Start the API server.

This method initializes the server and begins listening for incoming requests. It will block the current thread until the server is stopped.

Example

use rusty_api::Api;

let api = Api::new().start();

pub fn get_cert_path(&self) -> &str

Returns

A string representing the path to the certificate file.

use rusty_api::Api;

let api = Api::new().certs("path/to/cert.pem", "path/to/key.pem");
assert_eq!(api.get_cert_path(), "path/to/cert.pem");

pub fn get_key_path(&self) -> &str

Get the path to the TLS private key file.

Returns

A string representing the path to the private key file.

Example

use rusty_api::Api;

let api = Api::new().certs("path/to/cert.pem", "path/to/key.pem");
assert_eq!(api.get_key_path(), "path/to/key.pem");

pub fn get_addr(&self) -> &str

Get the address the server is bound to.
