Creates a new bundler from the given streams.

Source

pub fn positions(&self) -> CircuitPreprocessing

Elements delivered by every stream, per type.

Source

pub fn buffered(&self) -> CircuitPreprocessing

Elements currently buffered in every stream, per type.

Source

pub async fn resync( &self, targets: &CircuitPreprocessing, ) -> Result<(), AbortError>

Advances every stream to its per-type target. Rejects the whole call if any target is behind its stream’s position; otherwise dispatches all resyncs and joins them.

Source

pub fn buffer_configs(&self) -> PerStream<SharedBufferConfig>

The shared buffer config of every stream; itself a Buffer over the whole bundle.
