1//! Wallet Export Example
2//!
3//! This example demonstrates how to export a wallet's private key.
4//! ⚠️ **SECURITY WARNING**: This operation exposes sensitive private key material!
5//!
6//! It shows how to:
7//! - Initialize a Privy client with app credentials
8//! - Export wallet private keys with proper authorization
9//! - Handle export responses containing sensitive key data
10//!
11//! ## Required Environment Variables
12//! - `PRIVY_APP_ID`: Your Privy app ID
13//! - `PRIVY_APP_SECRET`: Your Privy app secret
14//! - `PRIVY_WALLET_ID`: The wallet ID to export
15//! - `PRIVY_AUTH_SIGNATURE`: Signature authorization (required)
16//!
17//! ## Usage
18//! ```bash
19//! cargo run --example wallet_export
20//! ```
