//! Generates a string session you can use for serverless deployments.
//!
//! A string session encodes your auth into a compact string so you can store
//! it in an env var or secret manager instead of a session file on disk.
//!
//! Run:
//!   cargo run --example string_session_gen
//!
//! After login, your session string is printed. Copy it and store it as the
//! SESSION_STRING env var for use with the serverless_userbot example.
//!
//! Keep the string private. It gives full access to your account.
