Enums

• FillNullStrategy
• TakeIdx
  One of the three arguments allowed in unchecked_take
• TakeRandBranch2
• TakeRandBranch3

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.
• ChunkCumAggcum_agg
• ChunkExpandAtIndex
  Create a new ChunkedArray filled with values at that index.
• ChunkExplode
  Explode/ flatten a List or Utf8 Series
• ChunkFillNullValue
  Replace None values with a value
• ChunkFilter
  Filter values by a boolean mask.
• ChunkFull
  Fill a ChunkedArray with one value.
• ChunkFullNull
• ChunkPeaks
  Find local minima/ maxima
• 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
  Fast access by index.
• ChunkUnique
  Get unique values in a ChunkedArray
• ChunkVar
  Variance and standard deviation aggregation.
• ChunkZip
  Combine two ChunkedArray based on some predicate.
• IntoTakeRandom
  Create a type that implements a faster TakeRandom.
• IsFirstis_first
  Mask the first unique values as true
• IsInis_in
  Check if element is member of list array
• IsLastis_last
  Mask the last unique values as true
• RepeatByrepeat_by
  Repeat the values n times.
• StrConcatconcat_str
  Concat the values into a string array.
• TakeIterator
• TakeIteratorNulls
• TakeRandom
  Random access
• TakeRandomUtf8

Type Definitions

• Dummy
  Dummy type, we need to instantiate all generic types, so we fill one with a dummy.
• FillNullLimit
