Enum polars_lazy::dsl::WindowMapping
source · pub enum WindowMapping {
GroupsToRows,
Explode,
Join,
}
Variants§
GroupsToRows
Map the group values to the position
Explode
Explode the aggregated list and just do a hstack instead of a join this requires the groups to be sorted to make any sense
Join
Join the groups as ‘List<group_dtype>’ to the row positions. warning: this can be memory intensive
