Trait OutputSink 

pub trait OutputSink:
    Send
    + Sync
    + 'static {
    // Required method
    fn push(&self, bytes: RVec<u8>) -> RResult<(), RString>;
}

Per-frame output sink for streaming plugins.

Crosses the dlopen boundary like FfiNode. The host hands an OutputSinkBox to FfiNode::process_streaming; the plugin invokes push() once per emission, and the host forwards each blob into its own streaming callback chain (router → next node → transport).

push takes &self because every realistic implementation (tokio mpsc senders, lock-free queues) has interior mutability — forcing &mut self would just push the synchronisation into the plugin’s callback closure.

push returns RErr if the host’s receiver was dropped mid-stream (session shutdown, barge-in). Plugins should treat that as “consumer is gone, unwind ASAP” rather than retrying.

Required Methods

fn push(&self, bytes: RVec<u8>) -> RResult<(), RString>

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
