Enum AttributeRegistrationError 

#[non_exhaustive]
pub enum AttributeRegistrationError {
    WrongSide,
    InvalidId,
    Duplicate,
    NotFinite,
    InvalidBounds,
}

Why a mod’s attribute type declaration was refused (Registrar::declare_attribute).

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 change the attribute registry.

InvalidId

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

Duplicate

Another declaration already covers the attribute.

NotFinite

The default or a bound is not finite.

InvalidBounds

min > max, or the default is not inside [min, max] (RangedAttribute’s own checks).
