Expand description

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

Provided Methods§

source

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.

source

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

Burn some item.

By default, this is not a supported operation.

source

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.

source

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.

Object Safety§

This trait is not object safe.
