Hello, I want to send a message along the prize to a user, is there a way to concatenate a string with a value? I tried it like this but it doesnt work: self.send().direct_egld( &winner_address, &prize, (b"You won the lottery with ID: {}! Congratulations!", &lottery_id), ); Any idea on how to add the "lottery_id" to the message?
We have a formatter that does this elegantly, although I never tried to format tx data. Should be something like sc_format("message {}", args) but I need to check
You are not really supposed to do string manipulations like these in a smart contract. You would have to write a method that can convert the number to the right ascii bytes.
