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

Provided Methods

fn mint_into( _item: &Self::ItemId, _who: &AccountId, _config: &ItemConfig, _deposit_collection_owner: bool, ) -> 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.

fn set_metadata( _who: &AccountId, _item: &Self::ItemId, _data: &[u8], ) -> DispatchResult

Set the metadata data of an item.

By default, this is not a supported operation.

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

Clear attribute of item’s key.

By default, this is not a supported operation.

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

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

By default this just attempts to use clear_attribute.

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

Clear the metadata of an item.

By default, this is not a supported operation.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
