Use your own authentication implementation

You do not need the sessions module for using the Firestore API of this crate. All Firestore methods in documents expect an object that implements the FirebaseAuthBearer trait.

That trait looks like this:

pub trait FirebaseAuthBearer<'a> {
    fn projectid(&'a self) -> &'a str;
    fn bearer(&'a self) -> &'a str;
}

Just implement this trait for your own data structure and provide the Firestore project id and a valid access token.
