Macro graphql_schema_from_str 

graphql_schema_from_str!() { /* proc-macro */ }

Evaluates to a Schema object given a literal Rust str containing GraphQL document text that represents a GraphQL schema.

This macro is effectively a compile-time version of SchemaBuilder::build_from_str().

Example usage:

use libgraphql::macros::graphql_schema_from_str;

let schema = graphql_schema_from_str!(r#"
    type Query {
        me: User,

    }

    type User {
        firstName: String,
        lastName: String,
    }
"#r);

let user_type =
    schema.defined_types()
        .get("User")
        .unwrap()
        .as_object()
        .unwrap();

assert_eq!(user_type.name(), "User");
assert_eq!(user_type.fields().get("firstName").is_some(), true);
assert_eq!(user_type.fields().get("firstName").is_some(), true);
assert_eq!(user_type.fields().get("doesntExist").is_some(), false);
