This happend out off the blue. After I did cargo clean, everything was fine again. This is probably because of a cache corruption then. But I am happy if this helps you guys anyways!

Code

Since this happend on a pretty big project of mine and I can't reproduce it, I sadly can't share a working reproduction example. But essentially, at the point of interrest, I am implementing a trait, which looks like this:

pub trait NodeTask: Send + Sync + 'static {
    type InputId: From<InputId> + Into<InputId>;
    type PipelineNode: PipelineNode;

    fn sync_node(&mut self, _node: &Self::PipelineNode) {}

    fn connect(&mut self, input_id: Self::InputId, input: &mut ConnectionHandle);

    fn disconnect(&mut self, input_id: Self::InputId);

    fn invalidate(&mut self) {}

    fn run(&mut self) -> impl Future<Output = ()> + Send;
}

On a struct similar to this:

struct Task {
    m_scan_out: TaskOutput<requests::Scan>,
    offset_in: TaskInput<requests::VectorData>,
}
// Every field is Send + Sync

Looks like #125945 which may have been fixed by #126409 already
