Function dataflow::render::threshold::build_threshold_basic [−][src]
pub fn build_threshold_basic<G, T>(
input: CollectionBundle<G, Row, T>,
key: Vec<MirScalarExpr>

Expand description
Build a dataflow to threshold the input data.
This implementation maintains rows in the output, i.e. all rows that have a count greater than zero. It returns a CollectionBundle populated from a local arrangement.
