pub type ColCollection<'scope, T> = Collection<'scope, T, Column<(Row, T, Diff)>>;Expand description
A columnar collection of (Row, Diff) updates, which is what a dataflow edge between
Plan nodes carries.
Aliased Type§
pub struct ColCollection<'scope, T> {
pub inner: Stream<'scope, T, Column<(Row, T, Overflowing<i64>)>>,
}Fields§
§inner: Stream<'scope, T, Column<(Row, T, Overflowing<i64>)>>The underlying timely dataflow stream.
This field is exposed to support direct timely dataflow manipulation when required, but it is not intended to be the idiomatic way to work with the collection.
Each update’s time is required to be greater or equal to some time in its container’s stamp, as documented on [Collection]. If this invariant is not upheld, differential operators may behave unexpectedly.
