Struct graphql_tools::validation::rules::no_unused_variables::NoUnusedVariables

pub struct NoUnusedVariables<'a> { /* private fields */ }

No unused fragments

A GraphQL operation is only valid if all variables defined by an operation are used, either directly or within a spread fragment.

See https://spec.graphql.org/draft/#sec-All-Variables-Used
