Struct PreCostContext

pub struct PreCostContext {}

Trait Implementations§

impl SpecificCostContextTrait<PreCost> for PreCostContext

fn to_cost_map(cost: PreCost) -> OrderedHashMap<CostTokenType, i64>

Converts a CostType to a OrderedHashMap from CostTokenType to i64.

fn into_full_cost_iter( cost: PreCost, ) -> impl Iterator<Item = (CostTokenType, i64)>

Converts a CostType to a OrderedHashMap from CostTokenType to i64. All relevant CostTokenType are included (even if their value is 0).

fn get_gas_withdrawal( &self, _idx: &StatementIdx, _branch_cost: &BranchCost, wallet_value: &PreCost, future_wallet_value: PreCost, ) -> Result<PreCost, CostError>

Computes the value that should be withdrawn and added to the wallet.

fn get_branch_requirement( &self, wallet_at_fn: &dyn Fn(&StatementIdx) -> WalletInfo<PreCost>, idx: &StatementIdx, branch_info: &BranchInfo, branch_cost: &BranchCost, ) -> WalletInfo<PreCost>

Returns the required value for the wallet for a single branch.
