}

Available on crate feature dynamic_group_by only.

Required Methods

fn rolling( &self, group_by: Option<Vec<[u64; 2]>>, options: &RollingGroupOptionsIR, ) -> Result<(Column, GroupPositions), PolarsError>

Returns the index values of the rows that get a window and one group per such row. options.placement is only supported without group_by.

fn group_by_dynamic( &self, group_by: Option<Vec<[u64; 2]>>, options: &DynamicGroupOptionsIR, ) -> Result<(Column, Vec<Column>, GroupPositions), PolarsError>

Returns: time_keys, keys, groupsproxy.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
