Enum CauldronRegistrationError 

#[non_exhaustive]
pub enum CauldronRegistrationError {
    Duplicate {
        owners: [String; 2],
    },
    UnknownItem,
    UnknownBlock,
    UnknownDispatcher,
    UnsupportedCapability,
}

A registration refused before the immutable dispatcher is published.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Duplicate

Both the existing and attempted owner, in that order.

UnknownItem

The item is absent from the prepared registry.

UnknownBlock

UnknownDispatcher

The requested dispatcher has not been declared.

UnsupportedCapability

The callback cannot cross the active runtime boundary.
