Struct RoutingFn 

pub struct RoutingFn<F>(pub F);

Wrapper for routing functions used with add_conditional_edges.

Wraps a function Fn(&JsonValue) -> String so it can be used directly as the path argument to add_conditional_edges.

use langgraph::prelude::*;
use langgraph_prebuilt::tools_condition;

graph.add_conditional_edges(
    "agent",
    RoutingFn(tools_condition),
    Some(HashMap::from([
        ("tools".to_string(), "tools".to_string()),
        (END.to_string(), END.to_string()),
    ])),
)?;
