How to define user configuration.

How can I add new user config settings.

Sorry for the delay on responding. What do you mean by user config settings?

If you're asking about a configuration file like nginx's, Pingora's current config files are more limited than nginx's and are limited to environment setup, e.g. see the (as-of-today) YAML formatted ServerConf and the user guide.

I mean extand ServerConf with my own configuration parameters.

I think your best bet is to use serde's ability to flatten de/serialized structures. Our serverconf is just a struct with a few derives. If you wanted to add some extra configurations to the same file, you could so something like

#[derive(Serialize, Deserialize)]
struct CombinedConf {
    // All pingora configurations come in here
    #[serde(flatten)]
    base_conf: ServerConf,

    // Any of your configurations can go here
    #[serde(flatten)]
    custom_conf: CustomConf,
}

#[derive(Serialize, Deserialize)]
struct CustomConf {
    awesomeness_count: f64
    // ...
}

For certain format like yaml and json you can even add your custom field directly into the server_conf.yaml

---
version: 1
threads: 2
awesomeness_count: 3

The yaml above can be directly deserialized to CustomConf. All the fields that are not in your CustomConf are ignored. All the custom fields are ignored by the ServerConf as well.
