Function export_wif 

pub fn export_wif(
    key: &PrivateKey,
    network: Network,
    compressed: bool,
) -> String

Export a private key to WIF format.

Example

use rustywallet_export::{export_wif, Network};
use rustywallet_keys::prelude::PrivateKey;

let key = PrivateKey::random();

// Compressed mainnet WIF (starts with K or L)
let wif = export_wif(&key, Network::Mainnet, true);
assert!(wif.starts_with('K') || wif.starts_with('L'));

// Uncompressed mainnet WIF (starts with 5)
let wif = export_wif(&key, Network::Mainnet, false);
assert!(wif.starts_with('5'));
