Absinthe.Type.NonNull (absinthe v1.5.4) View Source

A type that wraps an underlying type, acting identically to that type but adding a non-null constraint.

By default, all types in GraphQL are nullable. To declare a type that disallows null, wrap it in a Absinthe.Type.NonNull struct.

Examples

Given a type, :item, to declare it as non-null, you could do the following:

type: %Absinthe.Type.NonNull{of_type: :item}

But normally this would be done using Absinthe.Schema.Notation.non_null/1.

type: non_null(:item)
