Unable to define an associated functions named "new" that don’t have self as their first parameter

I’m getting the following error during cargo build. And I’m not sure how to resolve this.

error: not &self method
  --> src/new_service.rs:20:18
   |
20 |     pub async fn new() -> Self {
   |                  ^^^

relevant part of src/new_service.rs:

pub struct Service {
    start: Event,
    collections: Vec<Collection>,
    clients: Vec<Client>,
}

#[dbus_interface(name ="org.freedesktop.Secret.Service")]
impl Service {
    pub async fn new() -> Self {
        Service {
            start: event_listener::Event::new(),
            collections: Vec::new(),
            clients: Vec::new(),
        }
    }
.....

>Solution :

You can have multiple impl blocks for the same type, and that looks needed here since new wouldn’t be a callable DBus method. Try structuring your code like so:

pub struct Service {
    start: Event,
    collections: Vec<Collection>,
    clients: Vec<Client>,
}

impl Service {
    pub fn new() -> Self {
        Service {
            start: event_listener::Event::new(),
            collections: Vec::new(),
            clients: Vec::new(),
        }
    }
}

#[dbus_interface(name ="org.freedesktop.Secret.Service")]
impl Service {
    .....
}
