Command Handler

BotRS does not ship a command framework. The reference pattern is in examples/guild/command.rs: a small CommandRegistry mapping aliases to a fn(&str) -> Option<String>, dispatched from EventHandler::message_create.

The pattern

Build the registry once in your handler's constructor, then in each event call registry.try_execute(content) with the trimmed message text. The handler returns Some(reply) if it matched, None otherwise.

struct CommandRegistry { commands: Vec<(Vec<String>, fn(&str) -> Option<String>)> }

impl CommandRegistry {
    fn try_execute(&self, content: &str) -> Option<String> {
        let trimmed = content.trim();
        for (aliases, handler) in &self.commands {
            for alias in aliases {
                if trimmed.starts_with(alias) {
                    let params = trimmed[alias.len()..].trim();
                    return handler(params);
                }
            }
        }
        None
    }
}

The example registers two commands (你好 / hello and 晚安) and replies with session.reply(&response). Use send_markdown_message, send_embed_message, send_ark_message, or send_keyboard_message when a command returns a richer payload.
