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

Provided Methods

fn mint_into( _collection: &Self::CollectionId, _item: &Self::ItemId, _who: &AccountId, ) -> Result<(), DispatchError>

Mint some item of collection to be owned by who.

By default, this is not a supported operation.

fn burn( _collection: &Self::CollectionId, _item: &Self::ItemId, _maybe_check_owner: Option<&AccountId>, ) -> Result<(), DispatchError>

Burn some item of collection.

By default, this is not a supported operation.

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

Set attribute value of item of collection’s key.

By default, this is not a supported operation.

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

where K: Encode, V: Encode,

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

By default this just attempts to use set_attribute.

fn set_collection_attribute( _collection: &Self::CollectionId, _key: &[u8], _value: &[u8], ) -> Result<(), DispatchError>

Set attribute value of collection’s key.

By default, this is not a supported operation.

fn set_typed_collection_attribute<K, V>( collection: &Self::CollectionId, key: &K, value: &V, ) -> Result<(), DispatchError>

where K: Encode, V: Encode,

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

By default this just attempts to use set_attribute.

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.
