MakeThreadSafeObjectChangeset
@frozen
public struct MakeThreadSafeObjectChangeset<Upstream, T> : Publisher where Upstream : Publisher, T : ThreadConfined, Upstream.Output == ObjectChange<T>
A helper publisher created by calling .threadSafeReference()
on a publisher which emits thread-confined values.
-
Specifies the scheduler to deliver object changesets to.
This differs from
subscribe(on:)
in how it is integrated with the autorefresh cycle. When usingsubscribe(on:)
, the subscription is performed on the target scheduler and the publisher will emit the collection during the refresh. When usingreceive(on:)
, the collection is then converted to aThreadSafeReference
and delivered to the target scheduler with no integration into the autorefresh cycle, meaning it may arrive some time after the refresh occurs.When in doubt, you probably want
subscribe(on:)
