Struct mz_dataflow_types::LinearOperator
source · [−]pub struct LinearOperator {
pub predicates: Vec<MirScalarExpr>,
pub projection: Vec<usize>,
}
Expand description
In-place restrictions that can be made to rows.
These fields indicate optional information that may applied to streams of rows. Any row that does not satisfy all predicates may be discarded, and any column not listed in the projection may be replaced by a default value.
The intended order of operations is that the predicates are first applied, and columns not in projection can then be overwritten with default values. This allows the projection to avoid capturing columns used by the predicates but not otherwise required.
Fields
predicates: Vec<MirScalarExpr>
Rows that do not pass all predicates may be discarded.
projection: Vec<usize>
Columns not present in projection
may be replaced with
default values.
