Struct async_graphql::types::EmptyMutation

pub struct EmptyMutation;

Empty mutation

Only the parameters used to construct the Schema, representing an unconfigured mutation.

Examples

use async_graphql::*;

struct Query;

#[Object]
impl Query {
    async fn value(&self) -> i32 {
        // A GraphQL Object type must define one or more fields.
        100
    }
}

let schema = Schema::new(Query, EmptyMutation, EmptySubscription);
