pub fn poster_data_cost(&self, calldata_units: u64) -> Result<U256, ()>

pub fn compute_poster_cost( &self, poster: Address, tx_bytes: &[u8], brotli_compression_level: u64, ) -> Result<(U256, u64), ()>

Compute poster cost and units for a transaction on-chain.

Returns (l1_fee, units) where l1_fee = price_per_unit * units.

pub fn poster_data_cost_for_estimation( &self, tx_bytes: &[u8], brotli_compression_level: u64, ) -> Result<(U256, u64), ()>

Compute poster data cost for gas estimation (with padding).

Used when we don’t have an actual signed transaction, e.g. during eth_estimateGas. Applies padding to account for tx encoding overhead.

pub fn get_poster_units_without_cache( &self, tx_bytes: &[u8], brotli_compression_level: u64, ) -> u64

Compute the L1 calldata units for a transaction.

Compresses the tx bytes with brotli and multiplies by the EIP-2028 non-zero gas cost (16) to get the unit count.

pub fn update_for_batch_poster_spending<F>( &self, update_time: u64, current_time: u64, batch_poster: Address, wei_spent: U256, l1_basefee: U256, transfer_fn: F, ) -> Result<(), ()>

where F: FnMut(Address, Address, U256) -> Result<(), ()>,

Update pricing based on a batch poster spending report.
