Trait async_graphql_relay::RelayNodeInterface

pub trait RelayNodeInterfacewhere
    Self: Sized,{
    // Required method
    fn fetch_node<'async_trait>(
        ctx: RelayContext,
        relay_id: String

RelayNodeInterface is a trait implemented by the GraphQL interface enum to implement the fetch_node method. You should refer to the ‘RelayInterface’ macro which is the recommended way to implement this trait.

Required Methods

fn fetch_node<'async_trait>( ctx: RelayContext, relay_id: String ) -> Pin<Box<dyn Future<Output = Result<Self, Error>> + Send + 'async_trait>>where Self: 'async_trait,

fetch_node takes in a RelayContext and a generic relay ID and will return a Node interface with the requested object. This function is used to implement the ‘node’ query required by the Relay server specification for easily refetching an entity in the GraphQL schema.
