Gas burning abstraction for ArbOS operations.

Tracks multi-dimensional gas usage during ArbOS state modifications. SystemBurner is used for internal ArbOS operations that don’t have a notion of remaining gas.

Required Methods

fn burn(&mut self, kind: ResourceKind, amount: u64) -> Result<(), BurnError>

fn burn_multi_gas(&mut self, amount: MultiGas) -> Result<(), BurnError>

fn burned(&self) -> u64

fn gas_left(&self) -> u64

fn burn_out(&mut self) -> Result<(), BurnError>

fn restrict(&mut self, err: BurnError)

fn handle_error(&self, err: BurnError) -> Result<(), BurnError>

fn read_only(&self) -> bool

fn tracing_info(&self) -> Option<&TracingInfo>
