Implementations
impl HashAggregationHelper
[src]
pub fn update_each_row_states_by_offset<Src: BatchExecutor>(
entities: &mut Entities<Src>,

input_logical_rows: &[usize],
states: &mut [Box<dyn AggrFunctionState>],

[src]
entities: &mut Entities<Src>,
input_physical_columns: &mut LazyBatchColumnVec,
input_logical_rows: &[usize],
states: &mut [Box<dyn AggrFunctionState>],
states_offset_each_logical_row: &[usize]
) -> Result<()>
Updates states for each row.
Each row may belong to a different group. States of all groups should be passed in altogether in a single vector and the states of each row should be specified by an offset vector.
