Trait for providing an interface for NFT-like items which may be minted, burned and/or have attributes set on them.

Provided Methods

fn mint_into(_item: &Self::ItemId, _who: &AccountId) -> DispatchResult

Mint some item to be owned by who.

By default, this is not a supported operation.

fn burn(
    _item: &Self::ItemId,
    _maybe_check_owner: Option<&AccountId>
) -> DispatchResult

Burn some item.

By default, this is not a supported operation.

fn set_attribute(
    _item: &Self::ItemId,
    _key: &[u8],
    _value: &[u8]
) -> DispatchResult

Set attribute value of item’s key.

By default, this is not a supported operation.

fn set_typed_attribute<K: Encode, V: Encode>(
    item: &Self::ItemId,
    key: &K,
    value: &V
) -> DispatchResult

Attempt to set the strongly-typed attribute value of item’s key.

By default this just attempts to use set_attribute.
