Enum RegistryError 

#[non_exhaustive]
pub enum RegistryError {
    EmptyKind,
    DuplicateKind(String),
}

Registry mutation failure.

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.

EmptyKind

DuplicateKind(String)

Adapter kind is already registered.
