Crate lemon_graph
source ·Expand description
Async directed computation graphs, using petgraph.
§Usage
use lemon_graph::{Graph, Executor, nodes::{NodeWrapper, LogNode}};
#[tokio::main]
async fn main() {
let mut graph = Graph::new();
// Create a log node and set its message.
let log = LogNode::new(&mut graph);
let message = log.message(&graph).unwrap();
message.set_value(&mut graph, "Hello, world!".to_string().into());
// Create a second log node to run after the first.
let log_2 = LogNode::new(&mut graph);
log_2.run_after(&mut graph, log.0);
// Use the first log's message as input to the second log's message.
let message_2 = log_2.message(&graph).unwrap();
message_2.set_input(&mut graph, Some(message));
// Execute the graph.
Executor::execute(&mut graph, log.0).await.unwrap();
