Enum EntityAttributeError 

#[non_exhaustive]
pub enum EntityAttributeError {
    InvalidId,
    DuplicateAttribute,
    NotFinite,
    Duplicate,
}

Why an entity type’s attribute declaration or addition was refused (Registrar::declare_entity_attributes, Registrar::modify_entity_attributes).

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.

InvalidId

The entity type’s id is invalid or empty, or, for a declared set, in a namespace the declaring mod does not own.

DuplicateAttribute

The set names the same attribute twice.

NotFinite

A base value is not finite.

Duplicate

Another declaration already covers the entity type.
