Struct CallbackQuery 

pub struct CallbackQuery {
    pub raw: Update,
    pub state: State,
    /* private fields */
}

Update that bots receive when a user presses one of the bot’s inline callback buttons.

You should always CallbackQuery::answer these queries, even if you have no data to display to the user, because otherwise they will think the bot is non-responsive (the button spinner will timeout).

Fields

raw: Update

state: State

Implementations

impl CallbackQuery

pub fn peer_id(&self) -> PeerId

The Self::peer’s identifier.

pub async fn peer_ref(&self) -> Option<PeerRef>

Cached reference to the Self::peer, if it is in cache.

pub fn peer(&self) -> Option<&Peer>

The peer where the callback query occured, if it is in cache.

pub fn sender_id(&self) -> PeerId

The Self::sender’s identifier.

pub async fn sender_ref(&self) -> Option<PeerRef>

Cached reference to the Self::sender, if it is in cache.

pub fn sender(&self) -> Option<&Peer>

The user who sent this callback query, if it is in cache.

pub fn data(&self) -> &[u8]

They binary payload data contained by the inline button which was pressed.

This data cannot be faked by the client, since Telegram will only accept “button presses” on data that actually existed in the buttons of the message, so you do not need to perform any sanity checks.

Trivia: it used to be possible to fake the callback data, but a server-side check was added circa 2018 to prevent malicious clients from doing so.

pub fn is_from_inline(&self) -> bool

Whether the callback query was generated from an inline message.

pub async fn load_message(&self) -> Result<Message, InvocationError>

Load the Message that contains the pressed inline button.

pub fn answer(&self) -> Answer<'_>

Answer the callback query.
