Mint trait.

Provided Methods

fn mint(&mut self, initial_balance: U512) -> Result<URef, Error>

Mint 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>

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

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

Read balance of given purse.

fn transfer( &mut self, maybe_to: Option<AccountHash>, source: URef, target: URef, amount: U512, id: Option<u64> ) -> Result<(), Error>

Transfers amount of tokens from source purse to a target purse.

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

Retrieves the base round reward.

fn mint_into_existing_purse( &mut self, existing_purse: URef, amount: U512 ) -> Result<(), Error>

Mint amount new token into existing_purse. Returns unit on success, otherwise an error.
