Struct MessageBuilder 

pub struct MessageBuilder { /* private fields */ }

Builds a Message from styled spans.

Formatting is expressed as Telegram entities rather than as parse_mode markup, which means interpolated text is never parsed and therefore never needs escaping. A filename, a username, or an arbitrary error string can be passed straight through with no sanitizing step.
