### Set up AWS Nitro Enclave Server with Pontifex in Rust

Source: https://github.com/m1guelpf/pontifex/blob/main/README.md

This Rust code demonstrates how to build and run an AWS Nitro Enclave server using the `pontifex` library. It defines a port for listening, structures for request and response payloads, and uses `pontifex::listen` to asynchronously handle incoming connections. This setup requires the `server` feature enabled in the enclave's `Cargo.toml`.

```Rust
const ENCLAVE_PORT: u32 = 1000;

#[derive(serde::Deserialize)]
struct RequestPayload {}

#[derive(serde::Serialize)]
struct ResponsePayload {}

#[tokio::main]
async fn main() {
    // setup tracing, etc.

    tracing::info!("🦀 Starting server...");

    if let Err(e) = pontifex::listen(ENCLAVE_PORT, process).await {
        eprintln!("Failed to start server: {e}");
    }
}

async fn process(request: RequestPayload) -> ResponsePayload {
    // handle request

    ResponsePayload {}
}
```

### Send Requests to AWS Nitro Enclave Client with Pontifex in Rust

Source: https://github.com/m1guelpf/pontifex/blob/main/README.md

This Rust code illustrates how a client application can connect and send requests to an AWS Nitro Enclave using the `pontifex` library. It specifies the enclave's CID and port, defines request and response payload structures, and utilizes `pontifex::send` to transmit data and receive a response. This client setup requires the `client` feature enabled in its `Cargo.toml`.

```Rust
use pontifex::ConnectionDetails;

const ENCLAVE_CID: u32 = 100;
const ENCLAVE_PORT: u32 = 1024;

#[derive(serde::Serialize)]
struct RequestPayload {}

#[derive(serde::Deserialize)]
struct ResponsePayload {}

#[tokio::main]
async fn main() {

    let request = RequestPayload {};

    let result = pontifex::send::<RequestPayload, ResponsePayload>(ConnectionDetails::new(ENCLAVE_CID, ENCLAVE_PORT), &request).await;

    if let Ok(response) = result {
        println!("Response received");
    }
}
```
