Enum StorageErrorKind 

pub enum StorageErrorKind {
    Io,
    CorruptData,
    CorruptCrc,
    WalReplay,
    CatalogCorrupt,
    PageCorrupt,
    InvalidIdentifier,
    RowTooLarge,

    OverflowCorrupt,

    UniqueConstraintViolation,
    UniqueExpressionIndexViolation,
}

The kind of a StorageError, stripped of its payload.

StorageError can be neither Clone nor PartialEq because StorageError::Io wraps std::io::Error, which is neither. Callers that must keep a refusal around and branch on it later carry this instead of the error itself: the query layer stores it in QueryError::Storage beside the rendered message, and the server maps it to a wire error class.

StorageError::kind matches exhaustively, so a new StorageError variant does not compile until it has been given a kind here, and the server’s mapping from kind to wire class is exhaustive for the same reason. That is the whole point of the type: the class of an error a client acts on is decided by the compiler, not by a substring search over a message that anyone may reword.
