Based on Config. Auto-generated by #[pallet::config(with_default)]. Can be used in tandem with #[register_default_config] and #[derive_impl] to derive test config traits based on existing pallet config traits in a safe and developer-friendly way.

See here for more information and caveats about the auto-generated DefaultConfig trait and how it is generated.

Required Associated Types

type RuntimeEvent

The overarching event type.

type Balance: Member + Parameter + AtLeast32BitUnsigned + Default + Copy + MaybeSerializeDeserialize + MaxEncodedLen + TypeInfo

The units in which we record balances.

type RemoveItemsLimit: Get<u32>

Max number of items to destroy per destroy_accounts and destroy_approvals call.

Must be configured to result in a weight that makes each call fit in a block.

type AssetId: Member + Parameter + Clone + MaybeSerializeDeserialize + MaxEncodedLen

Identifier for the class of asset.

type AssetIdParameter: Parameter + From<Self::AssetId> + Into<Self::AssetId> + MaxEncodedLen

Wrapper around Self::AssetId to use in dispatchable call signatures. Allows the use of compact encoding in instances of the pallet, which will prevent breaking changes resulting from the removal of HasCompact from Self::AssetId.

This type includes the From<Self::AssetId> bound, since tightly coupled pallets may want to convert an AssetId into a parameter for calling dispatchable functions directly.

type AssetDeposit

The basic amount of funds that must be reserved for an asset.

type AssetAccountDeposit

The amount of funds that must be reserved for a non-provider asset account to be maintained.

type MetadataDepositBase

The basic amount of funds that must be reserved when adding metadata to your asset.

type MetadataDepositPerByte

The additional funds that must be reserved for the number of bytes you store in your metadata.

type ApprovalDeposit

The amount of funds that must be reserved when creating a new approval.

type StringLimit: Get<u32>

The maximum length of a name or symbol stored on-chain.

type Extra: Member + Parameter + Default + MaxEncodedLen

Additional data to be stored with an account’s asset balance.

type CallbackHandle: AssetsCallback<Self::AssetId, Self::AccountId>

Callback methods for asset state change (e.g. asset created or destroyed)

Types implementing the AssetsCallback can be chained when listed together as a tuple. The AutoIncAssetId callback, in conjunction with the NextAssetId, can be used to set up auto-incrementing asset IDs for this collection.

type WeightInfo: WeightInfo

Weight information for extrinsics in this pallet.

type BenchmarkHelper: BenchmarkHelper<Self::AssetIdParameter>

Helper trait for benchmarks.

Object Safety

This trait is not object safe.
