Struct StringCommandHandler 

pub struct StringCommandHandler { /* private fields */ }

Handler that matches messages whose text starts with /command.

Unlike CommandHandler, this handler does not require the message to have a bot_command entity. It performs a plain string prefix check on the message text.

Matching rules

1. The update must carry an effective message with non-empty text.
2. The text must start with /<command> (case-sensitive).
3. Arguments are the remaining words after the command.

Implementations

impl StringCommandHandler

pub fn new(command: String, callback: HandlerCallback, block: bool) -> Self

Create a new StringCommandHandler.

fn collect_additional_context( &self, _context: &mut CallbackContext, _match_result: &MatchResult, )

Populate additional context fields (e.g. context.args, context.matches) from the match result before the handler callback is invoked.

fn handle_update_with_context( &self, update: Arc<Update>, match_result: MatchResult, _context: CallbackContext, ) -> Pin<Box<dyn Future<Output = HandlerResult> + Send>>

Process the update with an Application-provided CallbackContext.
