//! Network type definitions
//!
//! This module provides the [`Network`] enum for distinguishing between
//! Bitcoin mainnet and testnet.

/// Blockchain network type.
///
/// Used to determine version bytes for WIF encoding and other network-specific
/// operations.
///
/// # Example
///
/// ```
/// use rustywallet_keys::network::Network;
///
/// let mainnet = Network::Mainnet;
/// assert_eq!(mainnet.wif_version_byte(), 0x80);
///
/// let testnet = Network::Testnet;
/// assert_eq!(testnet.wif_version_byte(), 0xEF);
/// ```
