# SDL Export

You can export your schema in Schema Definition Language (SDL) by using the `Schema::sdl()` method.


```rust
# extern crate async_graphql;
use async_graphql::*;

struct Query;

#[Object]
impl Query {
    async fn add(&self, u: i32, v: i32) -> i32 {
        u + v
    }
}

let schema = Schema::build(Query, EmptyMutation, EmptySubscription).finish();
    
// Print the schema in SDL format
println!("{}", &schema.sdl());
```
