Module traits 

Common traits for event producers and consumers.

These traits abstract over the different ring buffer types so that generic code can work with any combination of producer and consumer.

Trait	Role	Implementors
Sink	Accept events	RingBuf, seq_ring::Producer, event_buf::Producer
Source	Yield events	seq_ring::Consumer, event_buf::Consumer
Link	Both — accept and yield	Blanket impl for any Sink<In> + Source<Out>
LatestSink	Publish a newest value	latest_buf::Producer
LatestSource	Take the newest value with replacement/skipped evidence	latest_buf::Consumer

forward bridges Source into Sink only — the stream pair. LatestBuf’s handles implement the latest-value pair instead, by decision D2: try_pop cannot report the displacement that is that channel’s designed overload behaviour.

The free function forward transfers items from any Source to any Sink, stopping when the source is empty or the sink rejects a value.

Traits

LatestSink

Publish complete newest-state values with replacement evidence.

LatestSource

Take the latest complete state together with generation and gap evidence.

Link

A bidirectional pass-through: accepts In and yields Out.

Sink

Accept events.

Source

Yield events.

Functions

forward

Transfer up to max items from a Source into a Sink.
