Struct MountedNode 

pub struct MountedNode { /* private fields */ }

Handle for a node that has already been mounted into a runtime graph.

This is the Rust-native fast path: keep the handle around and update the mounted node directly instead of rebuilding and reconciling a new graph.

Fast-Path Updates

To enable efficient parameter updates:

1. Create a graph with keyed nodes: el::const_with_key("my_param", value)
2. Mount the graph: mounted = graph.mount()?
3. Retrieve the node by key: mounted.node_with_key("my_param")?
4. Send direct updates: mounted.node.set_const_value(new_value)

This avoids rebuilding and reconciling the entire graph on each parameter change.

Example

let mounted = Graph::new()
    .render(el::const_with_key("freq", 440.0))
    .mount();

// Update frequency without graph rebuild
if let Some(freq_node) = mounted.node_with_key("freq") {
    let update = freq_node.set_const_value(880.0);
    runtime.execute(&update);
}

Implementations
