GitHub - rasviitanen/rustysignal: Signal...

Hey guys trying to build a Signalling Server with Rust based on this repo: https://github.com/rasviitanen/rustysignal/tree/master Facing some issues when accounting for worker-rs instead. Here's some code: 
pub struct Node {
    pub owner: Option<String>,
    pub sender: WebSocket
}

impl Node {

    pub fn new(owner: Option<String>, sender: WebSocket) -> Self {
        Self { owner, sender }
    }
}

#[durable_object]
pub struct Network {
    pub nodemap: Vec<Node>,
    state: State, 
    env:Env,
}

#[durable_object]
impl DurableObject for Network {
    fn new(state: State, env: Env) -> Self {
        Self {
            nodemap: vec![],
            state: state, 
            env,
        }
    }

 
pub struct Node {
    pub owner: Option<String>,
    pub sender: WebSocket
}

impl Node {

    pub fn new(owner: Option<String>, sender: WebSocket) -> Self {
        Self { owner, sender }
    }
}

#[durable_object]
pub struct Network {
    pub nodemap: Vec<Node>,
    state: State, 
    env:Env,
}

#[durable_object]
impl DurableObject for Network {
    fn new(state: State, env: Env) -> Self {
        Self {
            nodemap: vec![],
            state: state, 
            env,
        }
    }
I notice that the durable object macro panics with this error: 
error[E0277]: the trait bound `Node: JsObject` is not satisfied
  --> src/lib.rs:15:1

How do I go about it?

This is interesting. I was able to reproduce your problem but only when the nodemap field is pub. Maybe this is just some random bug in the durable_object macro? can you get by keeping nodemap as private?

Hey radix. Yeah it works thanks!
