Provided Methods

unsafe fn _take_chunked_unchecked_seq( &self, idx: &[ChunkId], sorted: IsSorted, ) -> DataFrame

Take elements by a slice of ChunkIds.

Safety

Does not do any bound checks. sorted indicates if the chunks are sorted.

unsafe fn _take_opt_chunked_unchecked_seq(&self, idx: &[ChunkId]) -> DataFrame

Take elements by a slice of optional ChunkIds.

Safety

Does not do any bound checks.

unsafe fn _take_chunked_unchecked( &self, idx: &[ChunkId], sorted: IsSorted, ) -> DataFrame

Safety

Doesn’t perform any bound checks

unsafe fn _take_opt_chunked_unchecked(&self, idx: &[ChunkId]) -> DataFrame

Safety

Doesn’t perform any bound checks

Check for null state in ChunkId.
