pub struct FeePolicyManager { /* private fields */ }Expand description
The fee policy configuration of a network account: the policy defining the fee estimation for notes, which policies it may be switched to, and the asset that fees are charged in.
The actual fee computation logic is defined by a fee policy (e.g.
BasicConstantFeePolicy).
The AuthNetworkAccount component carries the
manager and adds the components of every registered policy when installed, so they do not
need to be installed separately. The FeePolicyManager is not an account component itself and
only exists to configure the auth component it is contained in.
Construct via Self::builder. The builder requires the fee faucet and the active fee policy.
Additional allowed policies for runtime switching may be registered.
Implementations§
Source§impl FeePolicyManager
impl FeePolicyManager
Sourcepub fn builder() -> FeePolicyManagerBuilder
pub fn builder() -> FeePolicyManagerBuilder
Builder constructor for FeePolicyManager.
The fee_faucet_id setter is required and sets the faucet issuing the fungible asset
fees are charged in. The active_fee_policy setter is required and registers the policy
the manager dispatches to. Each allowed_fee_policy setter registers an additional
reserved alternative for runtime switching via the set_fee_policy procedure.
Source§impl FeePolicyManager
impl FeePolicyManager
Sourcepub fn fee_asset_id(&self) -> AssetId
pub fn fee_asset_id(&self) -> AssetId
Returns the AssetId of the fungible asset fees are charged in.
Sourcepub fn active_fee_policy(&self) -> AccountProcedureRoot
pub fn active_fee_policy(&self) -> AccountProcedureRoot
Returns the active fee policy procedure root.
Sourcepub fn allowed_fee_policies(&self) -> Vec<AccountProcedureRoot>
pub fn allowed_fee_policies(&self) -> Vec<AccountProcedureRoot>
Returns all allowed fee policy procedure roots (active + reserved).
Sourcepub fn into_fee_policy_components(
self,
) -> impl Iterator<Item = AccountComponent>
pub fn into_fee_policy_components( self, ) -> impl Iterator<Item = AccountComponent>
Yields the AccountComponents contributed by every registered fee policy.
Sourcepub fn active_fee_policy_slot() -> &'static StorageSlotName
pub fn active_fee_policy_slot() -> &'static StorageSlotName
Returns the storage slot holding the active fee policy procedure root.
Sourcepub fn allowed_fee_policies_slot() -> &'static StorageSlotName
pub fn allowed_fee_policies_slot() -> &'static StorageSlotName
Returns the storage slot holding the map of allowed fee policy procedure roots.
Sourcepub fn fee_asset_id_slot() -> &'static StorageSlotName
pub fn fee_asset_id_slot() -> &'static StorageSlotName
Returns the storage slot holding the ID of the asset fees are charged in.
Sourcepub fn to_storage_slots(&self) -> [StorageSlot; 3]
pub fn to_storage_slots(&self) -> [StorageSlot; 3]
Builds the three fee-policy storage slots from this manager’s configuration:
- the active-policy value.
- the allowed-policies map.
- fee-asset value slot.
Exposed so tests and tooling can reproduce the fee-policy storage without building the full auth component.
Source§impl FeePolicyManager
impl FeePolicyManager
Sourcepub fn mock(fee_faucet_id: AccountId) -> FeePolicyManager
pub fn mock(fee_faucet_id: AccountId) -> FeePolicyManager
Returns a minimal single-policy manager charging fees in fee_faucet_id’s asset, for tests
that need a manager to construct an account but do not exercise the fee flow itself.
Its active policy is an empty BasicConstantFeePolicy, which aborts fee estimation for
any note script root; tests that consume notes need a policy with a fee schedule
instead.
