Struct perspective_viewer::utils::Subscriber
source · pub struct Subscriber<T: Clone>(/* private fields */);Expand description
Like a PubSub without PubSub::emit; the reciprocal of
PubSub::callback. Subscriber does not keep the parent PubSub alive.

fn tee<const N: usize>(self) -> <T as TeeInternal<N>>::Outputwhere
T: TeeInternal<N>,
Extension method to add
tee() method to all T: Clone. This can’t be
done directly as part of TeeInternal because it makes specifying the
const param at the tee() invocation site cumbersome:
TeeInternal::<N>::tee(&obj) as opposed to obj.tee::<N>(). The
constraint Self: TeeInternal<N> collapses the potential impl matches
to exactly 1, which makes the call to tee_internal() unambiguous.
This constraint is also allowed to contain the generic parameter N
because it is specified as a constraint to the method (as opposed to
a constraint on the trait). I’m honestly quite surprised this works … Read more
