Enum DatapackRegistrationError 

#[non_exhaustive]
pub enum DatapackRegistrationError {
    WrongSide,
    InvalidKey,
    Duplicate,
    InvalidFieldName,
    InvalidFieldKind,
    InvalidDefault,
}

Why a mod’s datapack registry declaration was refused (Registrar::declare_datapack_registry).

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.

WrongSide

Only both-side packages may declare datapack registries.

InvalidKey

The registry’s key is malformed, empty or in a namespace the declaring mod does not own (a vanilla registry’s included).

Duplicate

Another declaration already covers the registry key.

InvalidFieldName

A field name is empty or repeated.

InvalidFieldKind

A field’s kind is unusable: bounds that are not finite or min > max, a max_len of 0, or a reference to a malformed registry key.

InvalidDefault

A default is not a value of its field’s kind, or is out of its bounds.
