资产托盘配置特征的实现：

lib.rs：

parameter_types!{
    pub const StringLimit: u32 = 50;
    pub const MetadataDepositBase: Balance = 2 * DOLLARS ;
    pub const MetaDataDepositPerByte: Balance = 2 * DOLLARS ;
    //pub const AssetDepositBase: Balance = 2;
    pub const AssetDepositPerZombie: Balance = 2 * DOLLARS;
    pub const AssetDeposit: Balance = 2 * DOLLARS ;
    pub const ApprovalDeposit: Balance = 2 * DOLLARS ;
}


impl pallet_assets::pallet::Config for Runtime {
    // The ubiquitous event type.
    type Event= Event;
    type Balance= Balance;
    type AssetId= u32;
    type Currency = Balances;
    type ForceOrigin = EnsureRoot<AccountId>;
    type AssetDeposit = AssetDeposit;
    type ApprovalDeposit = ApprovalDeposit;
    type StringLimit = StringLimit;  
    //type AssetDepositBase=AssetDepositBase;
    //type AssetDepositPerZombie= AssetDepositPerZombie;
    type MetadataDepositBase = MetadataDepositBase;
    type MetadataDepositPerByte = MetaDataDepositPerByte;
    type Freezer = ();
    type Extra = ();
    type WeightInfo = pallet_assets::weights::SubstrateWeight<Runtime>;
