Trait Implementations§

source§

impl ChunkExpandAtIndex<BinaryOffsetType> for ChunkedArray<BinaryOffsetType>

source§

fn new_from_index( &self, index: usize, length: usize ) -> ChunkedArray<BinaryOffsetType>

Create a new ChunkedArray filled with values at that index.
source§

impl ChunkFilter<BinaryOffsetType> for ChunkedArray<BinaryOffsetType>

source§

fn filter( &self, filter: &ChunkedArray<BooleanType> ) -> Result<ChunkedArray<BinaryOffsetType>, PolarsError>

Filter values in the ChunkedArray with a boolean mask. Read more
source§

impl ChunkShift<BinaryOffsetType> for ChunkedArray<BinaryOffsetType>

source§

impl ChunkShiftFill<BinaryOffsetType, Option<&[u8]>> for ChunkedArray<BinaryOffsetType>

source§

fn shift_and_fill( &self, periods: i64, fill_value: Option<&[u8]> ) -> ChunkedArray<BinaryOffsetType>

Shift the values by a given period and fill the parts that will be empty due to this operation with fill_value.
source§

impl ChunkSort<BinaryOffsetType> for ChunkedArray<BinaryOffsetType>

source§

fn arg_sort_multiple( &self, by: &[Series], options: &SortMultipleOptions ) -> Result<ChunkedArray<UInt32Type>, PolarsError>

§Panics

This function is very opinionated. On the implementation of ChunkedArray<T> for numeric types, we assume that all numeric Series are of the same type.

In this case we assume that all numeric Series are f64 types. The caller needs to uphold this contract. If not, it will panic.

fn sort_with(&self, options: SortOptions) -> ChunkedArray<BinaryOffsetType>

source§

fn sort(&self, descending: bool) -> ChunkedArray<BinaryOffsetType>

Returned a sorted ChunkedArray.
source§

fn arg_sort(&self, options: SortOptions) -> ChunkedArray<UInt32Type>
