Function pallet_nfts::pallet::dispatchables::set_attribute

pub fn set_attribute<T: Config<I>, I: 'static>(
    collection: T::CollectionId,
    maybe_item: Option<T::ItemId>,
    namespace: AttributeNamespace<T::AccountId>,
    key: BoundedVec<u8, T::KeyLimit>,
    value: BoundedVec<u8, T::ValueLimit>
)

Set an attribute for a collection or item.

Origin must be Signed and must conform to the namespace ruleset:

• CollectionOwner namespace could be modified by the collection Admin only;
• ItemOwner namespace could be modified by the maybe_item owner only. maybe_item should be set in that case;
• Account(AccountId) namespace could be modified only when the origin was given a permission to do so;

The funds of origin are reserved according to the formula: AttributeDepositBase + DepositPerByte * (key.len + value.len) taking into account any already reserved funds.

• collection: The identifier of the collection whose item’s metadata to set.
• maybe_item: The identifier of the item whose metadata to set.
• namespace: Attribute’s namespace.
• key: The key of the attribute.
• value: The value to which to set the attribute.

Emits AttributeSet.
