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.
