Struct Call Many Budget &nbsp; Copy item path

impl CallManyBudget

pub fn new(calls: usize, gas_cap: u64) -> Result<CallManyBudget, EthApiError>

Creates the budget for a request of calls calls that share gas_cap gas.

Returns an error if calls exceeds DEFAULT_MAX_CALL_MANY_CALLS. A gas_cap of 0 disables the gas budget, as it disables the RPC gas cap.

pub fn for_bundles<T>( bundles: &[Bundle<T>], gas_cap: u64, ) -> Result<CallManyBudget, EthApiError>

Creates the budget for a request of bundles, see Self::new.

An empty bundle counts as one call, so requests of empty bundles are bounded too.

pub fn admit<T>(&mut self, tx_env: &mut Recovered<T>) -> Result<(), EthApiError>
where T: TransactionEnvMut,

Admits the request’s next call, lowering the gas limit of tx_env to the gas left for the request’s remaining calls.

The first admitted call starts the request’s timeout. Returns EthApiError::ExecutionTimedOut once it has expired.

pub fn map_call_err<E>(&self, err: E) -> E
where E: AsEthApiError + FromEthApiError,

Returns EthApiError::CallManyGasCapExceeded in place of err if the last admitted call failed its intrinsic gas check because Self::admit lowered its gas limit.

pub fn charge<E>(&mut self, result: &TxResultExt<E>) -> Result<(), EthApiError>

Charges the gas the last admitted call used against the budget.

Returns EthApiError::CallManyGasCapExceeded if the call ran out of gas after Self::admit lowered its gas limit, and an internal error if it used more gas than is left, which an admitted call cannot do.
