Required methods

fn transfer_purse_to_account(
    &mut self,
    source: URef,
    target: AccountHash,
    amount: U512
) -> Result<TransferredTo, Error>[src]

Transfers amount from source purse to a target account.

fn transfer_purse_to_purse(
    &mut self,
    source: URef,
    target: URef,
    amount: U512
) -> Result<(), Error>[src]

Transfers amount from source purse to a target purse.

fn balance(&mut self, purse: URef) -> Result<Option<U512>, Error>[src]

Checks balance of a purse. Returns None if given purse does not exist.

fn read_base_round_reward(&mut self) -> Result<U512, Error>[src]

Reads the base round reward.

fn mint(&mut self, amount: U512) -> Result<URef, Error>[src]

Mints new token with given initial_balance balance. Returns new purse on success, otherwise an error.

fn reduce_total_supply(&mut self, amount: U512) -> Result<(), Error>[src]

Reduce total supply by amount. Returns unit on success, otherwise an error.
