Required Associated Types§

Required Methods§

source

fn policies(&self) -> Self::PolicyIteratorType

Policies of the sender of the message. For init methods this is the would-be creator of the contract, for the receive this is the policies of the immediate sender.

In the latter case, if the sender is an account then it is the policies of the account, if it is a contract then it is the policies of the creator of the contract.
