Struct SinkedChain 

Source 
pub struct SinkedChain<DF, CurF, D, P, E, R>
where
    DF: RecFamily,
    CurF: RecFamily,
{ /* private fields */ }
Expand description

A fully specified chain, ready to build — or to stamp out one instance per pipeline thread via SinkedChain::build_factory.

Implementations§

Source§

impl<DF, CurF, D, P, E, R> SinkedChain<DF, CurF, D, P, E, R>
where DF: RecFamily, CurF: RecFamily, D: Deserializer<DF> + 'static, P: Assemble<SinkHandoff<CurF, E, R>>, <P as Assemble<SinkHandoff<CurF, E, R>>>::Out: for<'buf> Collector<<DF as RecFamily>::Rec<'buf>> + StageLifecycle + Send + 'static, E: RowEncoder<CurF> + Clone + 'static, R: ShardRouter + Send + 'static,

Source

pub fn build(self) -> Box<dyn RunnableChain>

Build one chain instance. Consumes the specification; the deserializer and router need no Clone, but the encoder does — the terminal stage mints one encoder per shard (columnar encoders hold per-block state that cannot be shared), and every in-tree encoder is Clone.

Source

pub fn build_factory(self) -> ChainFactory<DF, CurF, D, P, E, R>
where D: Clone, E: Clone, R: Clone,

Turn the specification into a factory producing one identical chain per pipeline thread.
