pub struct Notifications<'conn> {
    // some fields omitted
}

An iterator over asynchronous notifications.

Methods

impl<'conn> Notifications<'conn>

fn len(&self) -> usize

Returns the number of pending notifications.

fn iter<'a>(&'a self) -> Iter<'a>

Returns an iterator over pending notifications.

Note

This iterator may start returning Some after previously returning None if more notifications are received.

fn blocking_iter<'a>(&'a self) -> BlockingIter<'a>

Returns an iterator over notifications, blocking until one is received if none are pending.

The iterator will never return None.
