Module polars::chunked_array::ops

Traits for miscellaneous operations on ChunkedArray

Modules

• arity
• fill_null
• float_sorted_arg_max
  Implementations of the ChunkAgg trait.
• full
• gather
• search_sorted
• sort
• zipzip_with

Structs

• SortMultipleOptions
  Sort options for multi-series sorting.
• SortOptions
  Options for single series sorting.

Enums

• FillNullStrategy

Traits

• ChunkAgg
  Aggregation operations.
• ChunkAnyValue
• ChunkApply
  Fastest way to do elementwise operations on a ChunkedArray<T> when the operation is cheaper than branching due to null checking.
• ChunkApplyKernel
  Apply kernels on the arrow array chunks in a ChunkedArray.
• ChunkBytes
• ChunkCast
  Cast ChunkedArray<T> to ChunkedArray<N>
• ChunkCompare
  Compare Series and ChunkedArray’s and get a boolean mask that can be used to filter rows.
• ChunkExpandAtIndex
  Create a new ChunkedArray filled with values at that index.
• ChunkExplode
  Explode/flatten a List or String Series
• ChunkFillNullValue
  Replace None values with a value
• ChunkFilter
  Filter values by a boolean mask.
• ChunkFull
  Fill a ChunkedArray with one value.
• ChunkFullNull
• ChunkQuantile
  Quantile and median aggregation.
• ChunkReverse
  Reverse a ChunkedArray<T>
• ChunkRollApplyrolling_window
  This differs from ChunkWindowCustom and ChunkWindow by not using a fold aggregator, but reusing a Series wrapper and calling Series aggregators. This likely is a bit slower than ChunkWindow
• ChunkSet
  Create a ChunkedArray with new values by index or by boolean mask. Note that these operations clone data. This is however the only way we can modify at mask or index level as the underlying Arrow arrays are immutable.
• ChunkShift
• ChunkShiftFill
  Shift the values of a ChunkedArray by a number of periods.
• ChunkSort
  Sort operations on ChunkedArray.
• ChunkTake
• ChunkTakeUnchecked
• ChunkUnique
  Get unique values in a ChunkedArray
• ChunkVar
  Variance and standard deviation aggregation.
• ChunkZip
  Combine two ChunkedArray based on some predicate.
• IsFirstDistinctis_first_distinct
  Mask the first unique values as true
• IsLastDistinctis_last_distinct
  Mask the last unique values as true
• Reinterpretreinterpret
• SlicedArray
  Utility trait to slice concrete arrow arrays whilst keeping their concrete type. E.g. don’t return Box<dyn Array>.
