Struct ForceReply 

pub struct ForceReply {
    pub force_reply: bool,
    pub selective: Option<bool>,
}

Upon receiving a message with this object, Telegram clients will display a reply interface to the user (act as if the user has selected the bot‘s message and tapped ’Reply’). This can be extremely useful if you want to create user-friendly step-by-step interfaces without having to sacrifice privacy mode.

Fields

force_reply: bool

Shows reply interface to the user, as if they manually selected the bot‘s message and tapped ’Reply’

selective: Option<bool>

Optional. Use this parameter if you want to force reply from specific users only. Targets: 1) users that are @mentioned in the text of the Message object; 2) if the bot’s message is a reply (has reply_to_message_id), sender of the original message.
