    Missing,
    NotShredded,
}

Variants

Success(BorrowedShreddingState<'a>)

Path step succeeded, return the new shredding state

Missing

The path element is not present in the typed_value column and there is no value column, so we know it does not exist. It, and all paths under it, are all-NULL.

NotShredded

The path element is not present in the typed_value column and must be retrieved from the value column instead. The caller should be prepared to handle any value, including the requested type, an arbitrary “wrong” type, or Variant::Null.
