### Basic Secret Service Operations with Tokio

Source: https://github.com/open-source-cooperative/secret-service-rs/blob/master/README.md

Demonstrates initializing the SecretService, interacting with collections, creating, searching, retrieving, and deleting items. This example uses the tokio runtime.

```rust
use secret_service::SecretService;
use secret_service::EncryptionType;
use std::{collections::HashMap, error::Error};

#[tokio::main]
async fn main() -> Result<(), Box<dyn Error>> {
    // initialize secret service (dbus connection and encryption session)
    let ss = SecretService::connect(EncryptionType::Dh).await?;

    // get default collection
    let collection = ss.get_default_collection().await?;

    // create new item
    collection.create_item(
        "test_label", // label
        HashMap::from([("test", "test_value")]), // properties
        b"test_secret", // secret
        false, // replace item with same attributes
        "text/plain" // secret content type
    ).await?;

    // search items by properties
    let search_items = ss.search_items(
        HashMap::from([("test", "test_value")])
    ).await?;

    let item = search_items.unlocked.first().ok_or("Not found!")?;

    // retrieve secret from item
    let secret = item.get_secret().await?;
    assert_eq!(secret, b"test_secret");

    // delete item (deletes the dbus object, not the struct instance)
    item.delete().await?;
    Ok(())
}
```

### Add Secret Service Crate to Cargo.toml

Source: https://github.com/open-source-cooperative/secret-service-rs/blob/master/README.md

Specify the secret-service crate in your Cargo.toml file, selecting a feature flag for your desired runtime and cryptography backend. Ensure OpenSSL is available if using the -openssl feature.

```toml
[dependencies]
secret-service = { version = "5.0.0", features = ["rt-tokio-crypto-rust"] }
```
