Enum SelectionError 

#[non_exhaustive]
pub enum SelectionError {
    Fragment(FragmentError),
    Directive(DirectiveError),
}

Failure to reduce a document’s selection set to the fields it requests.

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.

Fragment(FragmentError)

A fragment spread could not be expanded.

Directive(DirectiveError)

A @skip/@include condition could not be evaluated.
