Configuration trait of this pallet.

The main purpose of this trait is to act as an interface between this pallet and the runtime in which it is embedded in. A type, function, or constant in this trait is essentially left to be configured by the runtime that includes this pallet.

Consequently, a runtime that wants to include this pallet must implement this trait.

Required Associated Types

type RuntimeEvent: From<Event<Self>> + IsType<<Self as Config>::RuntimeEvent>

type Balance: Parameter + Member + AtLeast32BitUnsigned + Default + Copy + MaybeSerializeDeserialize + MaxEncodedLen + TypeInfo + FixedPointOperand + Into<u128> + TryFrom<U256>

The balance type use Into<128> to supportd current impl of mangata-node pallets which rely on U256::from(value: u128) for arithemtics

type Amount: Signed + TryInto<Self::Balance> + TryFrom<Self::Balance> + Parameter + Member + SimpleArithmetic + Default + Copy + MaybeSerializeDeserialize + MaxEncodedLen + TypeInfo

The amount type, should be signed version of Balance

type CurrencyId: Parameter + Member + Copy + MaybeSerializeDeserialize + Ord + TypeInfo + MaxEncodedLen + Default + AtLeast32BitUnsigned + FullCodec

The currency ID type

type WeightInfo: WeightInfo

Weight information for extrinsics in this module.

type ExistentialDeposits: GetByKey<Self::CurrencyId, Self::Balance>

The minimum amount required to keep an account. It’s deprecated to config 0 as ED for any currency_id, zero ED will retain account even if its total is zero. Since accounts of orml_tokens are also used as providers of System::AccountInfo, zero ED may cause some problems.

type CurrencyHooks: MutationHooks<Self::AccountId, Self::CurrencyId, Self::Balance>

Hooks are actions that are executed on certain events. For example: OnDust, OnNewTokenAccount

type MaxLocks: Get<u32>

type MaxReserves: Get<u32>

The maximum number of named reserves that can exist on an account.

type ReserveIdentifier: Parameter + Member + MaxEncodedLen + Ord + Copy

The id type for named reserves.

type DustRemovalWhitelist: Contains<Self::AccountId>
