//! This example demonstrates how to use deep linking in Telegram
|
||||
//! by making a simple anonymous message bot.
|
||||
//!
|
||||
//! Deep linking (links like https://t.me/some_bot?start=123456789)
|
||||
//! is handled by telegram in the same way as just sending /start {argument}.
|
||||
//! So, in the StartCommand enum we need to write Start(String)
|
||||
//! to get the argument, just like in command.rs example.
|
||||
//!
|
||||
//! Also, deep linking is only supported with /start command!
|
||||
//! "https://t.me/some_bot?argument=123456789" will not work
|
||||
//!
