If you're working with Rust, the official Infisical Rust SDK package is the easiest way to fetch and work with secrets for your application.

### Installation

```bash
cargo add infisical
```

### Getting Started

The easiest way to get started is to use the builder pattern for both the client and your requests.

```rust
use infisical::{AuthMethod, Client, InfisicalError, encode_base64, decode_base64};
use infisical::secrets::GetSecretRequest;

async fn fetch_secret() -> Result<(), InfisicalError> {
    // 1. Build the client. You can chain methods to configure it.
    let mut client = Client::builder()
        .base_url("https://app.infisical.com") // Optional: defaults to https://app.infisical.com
        .build()
        .await?;

    // 2. Set up your authentication method and log in.
    let auth_method = AuthMethod::new_universal_auth("<your-client-id>", "<your-client-secret>");
    client.login(auth_method).await?;

    // 3. Build a request to get a secret.
    // Required parameters (name, project_id, environment) are passed to `builder()`.
    let request = GetSecretRequest::builder("API_KEY", "<your-project-id>", "dev")
        .path("/") // Optional parameters are set with builder methods.
        .build();

    // 4. Make the API call.
    let secret = client.secrets().get(request).await?;

    println!("Fetched secret key: {}", secret.secret_key);
    // For security, avoid printing the secret value in production code!
    // println!("Secret value: {}", secret.secret_value);

    Ok(())
}
```

### Client Configuration

The `Client::builder()` provides several configuration options:

```rust
let mut client = Client::builder()
    .base_url("https://app.infisical.com") // Optional: set custom Infisical instance URL
    .build()
    .await?;
```

**Parameters**
- `.base_url(url)`: Optional method to set the Infisical instance URL. Defaults to `https://app.infisical.com` for Infisical Cloud. Use `https://eu.infisical.com` for EU and `http://localhost:8080` for local development.

### Core Methods

The SDK methods are organized into the following high-level categories:

- `Client::builder()`: The main entry point for creating a client.
- `client.login()`: Allows client to make authenticated requests to the API.
- `client.secrets()`: Provides access to all CRUD operations for secrets.
- `client.kms()`: Provides access to all KMS (Key Management Service) operations.

### Helper Functions

The SDK provides utility functions for common operations:

```rust
use infisical::{encode_base64, decode_base64};

// Base64 encode a string
let encoded = encode_base64("sensitive data");
println!("Encoded: {}", encoded);

// Base64 decode a string
let decoded = decode_base64(&encoded)?;
println!("Decoded: {}", decoded);
```

**Available Functions**
- `encode_base64(data: &str) -> String`: Encodes a string as base64
- `decode_base64(data: &str) -> Result<String, InfisicalError>`: Decodes a base64 string

### `secrets`

All secret operations are accessed via `client.secrets()`. Each operation has a dedicated request builder.

#### Create Secret

    "<your-project-id>",
    "dev"
)
.path("/")
.secret_comment("A comment for the new secret")
.build();

let created_secret = client.secrets().create(request).await?;
```

## Development and Testing

### Environment Setup

For development and testing, you'll need to set up environment variables. Create a `.env` file in your project root:

```env
INFISICAL_CLIENT_ID=your_client_id_here
INFISICAL_CLIENT_SECRET=your_client_secret_here
INFISICAL_BASE_URL=http://localhost:8080  # Optional: for local development

# Project IDs for different resources
INFISICAL_SECRETS_PROJECT_ID=your_project_id_here
INFISICAL_KMS_PROJECT_ID=your_project_id_here
```

### Getting Credentials

To obtain the required credentials:

1. **Client ID and Secret**: Create a Universal Auth machine identity in your Infisical project settings
2. **Project ID**: Found in your project settings or URL when viewing a project in the Infisical dashboard

### Running Tests

Tests that require authentication are marked with `#[ignore]` and need valid credentials:

```bash
# Run ignored tests (requires .env file with valid credentials)
cargo test -- --ignored --nocapture

# Run a specific test
cargo test test_kms_resource -- --ignored --nocapture
```

**Note**: Integration tests require a running Infisical instance and valid authentication credentials.
