wasmCloud GraphDB Actor Interface
This crate provides an abstraction over the wasmcloud:graphdb
contract. This
allows actors to interact with a graph database, such as RedisGraph or Neo4j.
Example:
use serde_json::json;
extern crate wapc_guest as guest;
use wasmcloud_actor_graphdb as graph;
use graph::*;
use wasmcloud_actor_http_server as http;
use wasmcloud_actor_core as actor;
use guest::prelude::*;
#[actor::init]
pub fn init() {
http::Handlers::register_handle_request(handle_http_request);
}
fn handle_http_request(_: http::Request) -> HandlerResult<http::Response> {
// Replace `query_db` with `graph::default().query_graph()`
let (name, birth_year): (String, u32) = query_db(
"MotoGP".to_string(),
"MATCH (r:Rider)-[:rides]->(t:Team) WHERE t.name = 'Yamaha' RETURN r.name, r.birth_year"
.to_string(),
)?;
assert_eq!(name, "Alice Rider".to_string());
assert_eq!(birth_year, 1985);
let result = json!({
"name": name,
"birth_year": birth_year
});
Ok(http::Response::json(result, 200, "OK"))
}
