Fluent interface methods should move the receiver

[Inityx]

Many structs such as SendMessage implement a fluent interface for customization. The methods mutate in place, taking &mut self and returning &mut self. This forces a mutable binding of the original:

fn message() -> SendMessage {
    let mut message = SendMessage(CHAT, "<b>Hello</b>");
    message.parse_mode(ParseMode::Html);
    message
}

let mut message = message();
api.send(message.disable_notification()).await

These methods should instead move self, and allow chaining the methods in a single expression:

fn message() -> SendMessage {
    SendMessage(CHAT, "<b>Hello</b>").parse_mode(ParseMode::Html)
}

let message = message().disable_notification();
api.send(message).await
