Expand description

Entry in a GraphQL selection set

This enum represents one of the three variants of a selection that exists in GraphQL: a field, a fragment spread, or an inline fragment. Each of the variants references their location in the query source.

{
  field(withArg: 123) { subField }
  ...fragmentSpread
  ...on User {
    inlineFragmentField
  }
}

Variants

`Field(Spanning<Field<'a, S>>)`

`FragmentSpread(Spanning<FragmentSpread<'a, S>>)`

`InlineFragment(Spanning<InlineFragment<'a, S>>)`
