Expand description
Trait for providing an interface for NFT-like assets which may be minted, burned and/or have attributes set on them.
Provided methods
fn mint_into(_instance: &Self::InstanceId, _who: &AccountId) -> DispatchResult
fn mint_into(_instance: &Self::InstanceId, _who: &AccountId) -> DispatchResultMint some asset instance to be owned by who.
By default, this is not a supported operation.
fn burn_from(_instance: &Self::InstanceId) -> DispatchResult
fn burn_from(_instance: &Self::InstanceId) -> DispatchResultBurn some asset instance.
By default, this is not a supported operation.
fn set_attribute(
_instance: &Self::InstanceId,
_key: &[u8],
_value: &[u8]
) -> DispatchResult
fn set_attribute(
_instance: &Self::InstanceId,
_key: &[u8],
_value: &[u8]
) -> DispatchResultSet attribute value of asset instance’s key.
By default, this is not a supported operation.
fn set_typed_attribute<K: Encode, V: Encode>(
instance: &Self::InstanceId,
key: &K,
value: &V
) -> DispatchResult
fn set_typed_attribute<K: Encode, V: Encode>(
instance: &Self::InstanceId,
key: &K,
value: &V
) -> DispatchResultAttempt to set the strongly-typed attribute value of instance’s key.
By default this just attempts to use set_attribute.
