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

Provided methods

fn mint_into(
    _class: &Self::ClassId,
    _instance: &Self::InstanceId,
    _who: &AccountId
) -> DispatchResult

Mint some asset instance of class to be owned by who.

By default, this is not a supported operation.

fn burn_from(
    _class: &Self::ClassId,
    _instance: &Self::InstanceId
) -> DispatchResult

Burn some asset instance of class.

By default, this is not a supported operation.

fn set_attribute(
    _class: &Self::ClassId,
    _instance: &Self::InstanceId,
    _key: &[u8],
    _value: &[u8]
) -> DispatchResult

Set attribute value of asset instance of class’s key.

By default, this is not a supported operation.

fn set_typed_attribute<K: Encode, V: Encode>(
    class: &Self::ClassId,
    instance: &Self::InstanceId,
    key: &K,
    value: &V
) -> DispatchResult

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

By default this just attempts to use set_attribute.

fn set_class_attribute(
    _class: &Self::ClassId,
    _key: &[u8],
    _value: &[u8]
) -> DispatchResult

Set attribute value of asset class’s key.

By default, this is not a supported operation.

fn set_typed_class_attribute<K: Encode, V: Encode>(
    class: &Self::ClassId,
    key: &K,
    value: &V
) -> DispatchResult

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

By default this just attempts to use set_attribute.
