Struct VisitObservation

pub struct VisitObservation {
    pub url: Url,
    pub title: Option<String>,
    pub visit_type: Option<VisitType>,
    pub is_error: Option<bool>,
    pub is_redirect_source: Option<bool>,
    pub is_permanent_redirect_source: Option<bool>,
    pub at: Option<Timestamp>,
    pub referrer: Option<Url>,
    pub is_remote: Option<bool>,
    pub preview_image_url: Option<Url>,
}

An “observation” based model for updating history. You create a VisitObservation, call functions on it which correspond with what you observed. The page will then be updated using this info.

It’s implemented such that the making of an “observation” is itself significant - it records what specific changes should be made to storage. For example, instead of simple bools with defaults (where you can’t differentiate explicitly setting a value from the default value), we use Option, with the idea being it’s better for a store shaped like Mentat.

It exposes a “builder api”, but for convenience, that API allows Options too. So, eg, .with_title(None) or with_is_error(None) is allowed but records no observation.
