Function init_sdk 

pub fn init_sdk() -> Result<(), JsValue>

Initializes Telegram WebApp SDK by extracting and validating context.

• Parses initData (urlencoded) with embedded JSON.
• Parses themeParams (object).
• Initializes global context.

Errors

Returns Err(JsValue) in the following cases:

• WindowUnavailable: No browser window object found
• TelegramUnavailable: window.Telegram is undefined
• WebAppUnavailable: Telegram.WebApp is undefined
• InitDataParseFailed: Failed to parse WebApp.initData
• ThemeParamsParseFailed: Failed to parse theme parameters
• ContextInitFailed: Failed to initialize global context

Examples

use telegram_webapp_sdk::core::init::init_sdk;

match init_sdk() {
    Ok(_) => println!("SDK initialized successfully"),
    Err(e) => eprintln!("Initialization failed: {:?}", e)
}

For better error handling, consider using try_init_sdk which returns typed InitError.
