+description: A bring your own types GraphQL client for Rust
+url: https://cynic-rs.dev
+github: obmarg/cynic
+---
+
+A client library for rust that generates queries from types you provide,
+verifying that the types match the shape of your schema.
+
+It provides [a generator](https://generator.cynic-rs.dev) to bootstrap types
+from existing GraphQL queries.
+
+Usage example:
+
+```rust
+#[derive(cynic::QueryFragment, Debug)]
+#[cynic(
+    schema_path = "../schemas/starwars.schema.graphql",
+    query_module = "query_dsl",
+    graphql_type = "Root",
+    argument_struct = "FilmArguments"
+)]
+struct FilmDirectorQuery {
+    #[arguments(id = &args.id)]
+    film: Option<Film>,
+}
+
+#[derive(cynic::QueryFragment, Debug)]
+#[cynic(
+    schema_path = "../schemas/starwars.schema.graphql",
+    query_module = "query_dsl",
+    graphql_type = "Film"
+)]
+struct Film {
+    title: Option<String>,
+    director: Option<String>,
+}
+
+#[derive(cynic::FragmentArguments)]
+struct FilmArguments {
+    id: Option<cynic::Id>,
+}
+
+fn main() {
+    use cynic::{QueryBuilder, http::ReqwestBlockingExt};
+
+    let query = FilmDirectorQuery::build(&FilmArguments {
+        id: Some("ZmlsbXM6MQ==".into()),
+    })
+
+    reqwest::blocking::Client::new()
+        .post("https://swapi-graphql.netlify.com/.netlify/functions/index")
+        .run_graphql(query)
+        .unwrap()
+}
+
+mod query_dsl {
+    cynic::query_dsl!("../schemas/starwars.schema.graphql");
+}
+```
