Cynic - A GraphQL Client For Rust

Sending HTTP Request Manually

The cynic::http module provides integrations for some HTTP clients, but sometimes you might want to make a request manually: either because you're using a client that cynic doesn't support, or the provided integrations just aren't sufficient in some way.

It's simple to make an HTTP query manually with cynic:

• cynic::Operation implements serde::Serialize to build the body of a GraphQL request. This can be used with whatever JSON encoding functionality your HTTP client provides.
• The cynic::QueryFragment derive generates a serde::Deserialize impl that you can use to deserialize a cynic::GraphQlResponse<YourQueryFragment>

For instance, to make a request with the reqwest::blocking client:

#![allow(unused)]
fn main() {
use cynic::{QueryBuilder, GraphQlResponse};

let operation = AllFilmsQuery::build(());

let response = reqwest::blocking::Client::new()
    .post("https://swapi-graphql.netlify.app/.netlify/functions/index")
    .json(&operation)
    .send()
    .unwrap();

let all_films_result = response.json::<GraphQlResponse<AllFilmsQuery>>().unwrap();
}

Now you can do whatever you want with the result.
