Struct GraphqlExecutor 

pub struct GraphqlExecutor { /* private fields */ }

Executes simplified GraphQL queries against an EntityStore.

Usage

use std::sync::Arc;
use chainindex_core::entity::MemoryEntityStore;
use chainindex_core::graphql::GraphqlExecutor;

let store = Arc::new(MemoryEntityStore::new());
let executor = GraphqlExecutor::new(store);
let resp = executor.execute(r#"{ transfers(first: 5) { id } }"#).await;

Implementations

impl GraphqlExecutor

pub fn new(store: Arc<dyn EntityStore>) -> Self

Create a new executor backed by the given entity store.

pub fn register_schema(&self, entity_schema: EntitySchema)

Register an entity schema so the executor knows the field list.

pub fn introspect(&self) -> String

Return the SDL for all registered entity types (introspection).

pub async fn execute(&self, query: &str) -> GraphqlResponse

Execute a GraphQL query string and return a GraphqlResponse.
