Module schema 

Using Schema Definitions

The graphql_query::schema module contains utilities to create a GraphQL Schema or parse it from introspection data. This information may then be used to validate and introspect a schema as to possible queries that may be written against it.

The BuildClientSchema trait may be used to convert introspection data into a usable Schema, which may then be used to inspect GraphQL defnitions:

use graphql_query::{ast::ASTContext, schema::*};

fn inspect() {
    let ctx = ASTContext::new();

    let introspection_json = include_str!("../../fixture/introspection_query.json");
    let introspection: IntrospectionQuery = serde_json::from_str(introspection_json).unwrap();
    let _schema = introspection.build_client_schema(&ctx);
}
