Struct IptsManagerView

pub(crate) struct IptsManagerView {
    shared: Arc<Mutex<PublishIptSet>>,
    notify: Sender<()>,
}

Shared view of introduction points - IPT manager’s view

This is the manager’s end of a bidirectional “channel”, containing a shared PublishIptSet, i.e. an Option<IptSet>.

Fields

shared: Arc<Mutex<PublishIptSet>>

Actual shared data

notify: Sender<()>

Notification sender

We don’t wrap the state in a postage::watch, because the publisher needs to be able to mutably borrow the data without re-notifying itself when it drops the guard.

Implementations

impl IptsManagerView

pub(crate) fn borrow_for_update( &mut self, runtime: impl SleepProvider, ) -> impl DerefMut<Target = PublishIptSet> + '_

Arrange to be able to update the list of introduction points

The manager may add new ipts, or delete old ones.

The returned value is a lock guard. (It is not Send so cannot be held across await points.) The publisher will be notified when it is dropped.

pub(crate) fn borrow_for_read( &mut self, ) -> impl Deref<Target = PublishIptSet> + '_

Peek at the list of introduction points we are providing to the publisher

(Used for testing and during startup.)
