Struct StringSessionBackend 

pub struct StringSessionBackend { /* private fields */ }

Portable base64 string session backend — Pyrogram/Telethon style.

The session is stored as a single URL-safe base64 string with no padding. Useful for deployment pipelines, Docker, environment variables, and CI bots.

Example

let session_str = std::env::var("SESSION").unwrap();
let backend = StringSessionBackend::new(&session_str);
// ... pass to Config::session_backend

// Later, export the updated session:
let updated = backend.current();
println!("SESSION={updated}");

Implementations

impl StringSessionBackend

pub fn new(s: impl Into<String>) -> Self

Create a backend pre-loaded from an existing session string. Pass an empty string to start a fresh session.

pub fn current(&self) -> String

Return the current encoded session string. Call after client.save_session() to get the latest value.
