Counters owner can change gas limit and allowance counters.

Required Methods

fn charge_gas_for_token(&mut self, token: CostToken) -> Result<(), ChargeError>

Charge for runtime api call.

fn charge_gas_if_enough(&mut self, amount: u64) -> Result<(), ChargeError>

Charge gas if enough, else just returns error.

fn gas_left(&self) -> GasLeft

Returns gas limit and gas allowance left.

fn current_counter_type(&self) -> CounterType

Currently set gas counter type.

fn decrease_current_counter_to(&mut self, amount: u64)

Decreases gas left by fetched single numeric of actual counter.

fn define_current_counter(&mut self) -> u64

Returns minimal amount of gas counters and set the type of current counter.

Provided Methods

fn current_counter_value(&self) -> u64

Returns value of gas counter currently set.
