//! # Webcash Wallet Library
//!
//! A secure, efficient Rust implementation of the Webcash electronic cash wallet.
//!
//! This library provides:
//! - Deterministic HD wallet functionality
//! - Secure storage using SQLite with biometric encryption
//! - Server communication for Webcash operations
//! - Biometric authentication (Face ID/Touch ID on iOS, Biometric API on Android)
//! - State-of-the-art cryptographic security with hardware RNG
//! - C bindings for interoperability
//!
//! ## Example
//!
//! ```rust,no_run
//! use webylib::{Wallet, SecretWebcash};
//!
//! # async fn example() -> Result<(), Box<dyn std::error::Error>> {
//! // Create or open a wallet
//! let wallet = Wallet::open("my_wallet.db").await?;
//!
//! // Insert webcash
//! let webcash = SecretWebcash::parse("e1.00000000:secret:abcdef123456...")?;
//! wallet.insert(webcash).await?;
//!
//! // Check balance
//! let balance = wallet.balance().await?;
//! println!("Balance: {}", balance);
//! # Ok(())
//! # }
//! ```
