You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: client.rs
    path of file: ./repos/backend/crates/core/database/src/events
    
    the code of the file until where you have to start completion: use authifier::AuthifierEvent;
use serde::{Deserialize, Ser
    
    pub async fn p_user(self, id: String, db: &Database) {
        self.clone().p(id.clone()).await;

        // TODO: this should be captured by member list in the future and not immediately fanned out to users
        if let Ok(members) = db.fetch_all_memberships(&id).await {
            for member in members {
                self.clone().p(member.id.server).await;
            }
        }
    }
