Storage functions

---

AssetBalance

asset balance for user&asset_id, use btree_map to accept different asset type

Python

result = substrate.query(
    'XAssets', 'AssetBalance', ['AccountId', 'u32']
)

Return value

'scale_info::259'

---

AssetRestrictionsOf

asset extend limit properties, set asset "can do", example, CanTransfer, CanDestroyWithdrawal notice if not set AssetRestriction, default is true for this limit if want let limit make sense, must set false for the limit

Python

result = substrate.query(
    'XAssets', 'AssetRestrictionsOf', ['u32']
)

Return value

{'bits': 'u32'}

---

TotalAssetBalance

asset balance for an asset_id, use btree_map to accept different asset type
