Trait tor_netdir::NetDirProvider

pub trait NetDirProvider: UpcastArcNetDirProvider + Send + Sync {
    // Required methods
    fn netdir(&self, timeliness: Timeliness) -> Result<Arc<NetDir>>;
    fn events(&self) -> BoxStream<'static, DirEvent>;
    fn params(&self) -> Arc<dyn AsRef<NetParameters>>;

    // Provided method
    fn timely_netdir(&self) -> Result<Arc<NetDir>> { ... }
}

An object that can provide NetDirs, as well as inform consumers when they might have changed.

Required Methods

fn netdir(&self, timeliness: Timeliness) -> Result<Arc<NetDir>>

Return a network directory that’s live according to the provided timeliness.

fn events(&self) -> BoxStream<'static, DirEvent>

Return a new asynchronous stream that will receive notification whenever the consensus has changed.

Multiple events may be batched up into a single item: each time this stream yields an event, all you can assume is that the event has occurred at least once.

fn params(&self) -> Arc<dyn AsRef<NetParameters>>

Return the latest network parameters.

If we have no directory, return a reasonable set of defaults.

Provided Methods

fn timely_netdir(&self) -> Result<Arc<NetDir>>

Return a reasonable netdir for general usage.

This is an alias for NetDirProvider::netdir(Timeliness::Timely).
