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, ) -> Result<(), DispatchError>

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>, ) -> Result<(), DispatchError>

Burn some item.

By default, this is not a supported operation.

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

Set attribute value of item’s key.

By default, this is not a supported operation.

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

where K: Encode, V: Encode,

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

By default this just attempts to use set_attribute.

Object Safety

This trait is not object safe.
