Struct polars::chunked_array::ChunkedArray

pub struct ChunkedArray<T>where
    T: PolarsDataType,{ /* private fields */ }

ChunkedArray

Every Series contains a ChunkedArray<T>. Unlike Series, ChunkedArray’s are typed. This allows us to apply closures to the data and collect the results to a ChunkedArray of the same type T. Below we use an apply to use the cosine function to the values of a ChunkedArray.

fn apply_cosine(ca: &Float32Chunked) -> Float32Chunked {
    ca.apply(|v| v.cos())
}

If we would like to cast the result we could use a Rust Iterator instead of an apply method. Note that Iterators are slightly slower as the null values aren’t ignored implicitly.

fn apply_cosine_and_cast(ca: &Float32Chunked) -> Float64Chunked {
    ca.into_iter()
        .map(|opt_v| {
        opt_v.map(|v| v.cos() as f64)
    }).collect()
}

Another option is to first cast and then use an apply.

fn apply_cosine_and_cast(ca: &Float32Chunked) -> Float64Chunked {
    ca.apply_cast_numeric(|v| v.cos() as f64)
}

Conversion between Series and ChunkedArray’s

Conversion from a Series to a ChunkedArray is effortless.

fn to_chunked_array(series: &Series) -> PolarsResult<&Int32Chunked>{
    series.i32()
}

fn to_series(ca: Int32Chunked) -> Series {
    ca.into_series()
}

Iterators

ChunkedArrays fully support Rust native Iterator and DoubleEndedIterator traits, thereby giving access to all the excellent methods available for Iterators.

fn iter_forward(ca: &Float32Chunked) {
    ca.into_iter()
        .for_each(|opt_v| println!("{:?}", opt_v))
}

fn iter_backward(ca: &Float32Chunked) {
    ca.into_iter()
        .rev()
        .for_each(|opt_v| println!("{:?}", opt_v))
}

Memory layout

ChunkedArray’s use Apache Arrow as backend for the memory layout. Arrows memory is immutable which makes it possible to make multiple zero copy (sub)-views from a single array.

To be able to append data, Polars uses chunks to append new memory locations, hence the ChunkedArray<T> data structure. Appends are cheap, because it will not lead to a full reallocation of the whole array (as could be the case with a Rust Vec).

However, multiple chunks in a ChunkArray will slow down many operations that need random access because we have an extra indirection and indexes need to be mapped to the proper chunk. Arithmetic may also be slowed down by this. When multiplying two ChunkArray's with different chunk sizes they cannot utilize SIMD for instance.

If you want to have predictable performance (no unexpected re-allocation of memory), it is advised to call the ChunkedArray::rechunk after multiple append operations.

See also ChunkedArray::extend for appends within a chunk.

Implementations

impl<T> ChunkedArray<T>where T: PolarsNumericType, <T as PolarsNumericType>::Native: Signed,

pub fn abs(&self) -> ChunkedArray<T>

Convert all values to their absolute/positive value.

impl<T> ChunkedArray<T>where T: PolarsNumericType,

pub fn append(&mut self, other: &ChunkedArray<T>)

Append in place. This is done by adding the chunks of other to this ChunkedArray.

See also extend for appends to the underlying memory

impl<T> ChunkedArray<T>where T: PolarsNumericType,

pub fn cast_and_apply_in_place<F, S>(&self, f: F) -> ChunkedArray<S>where F: Fn(<S as PolarsNumericType>::Native) -> <S as PolarsNumericType>::Native + Copy, S: PolarsNumericType,

Cast a numeric array to another numeric data type and apply a function in place. This saves an allocation.

impl<T> ChunkedArray<T>where T: PolarsNumericType,

pub fn apply_mut<F>(&mut self, f: F)where F: Fn(<T as PolarsNumericType>::Native) -> <T as PolarsNumericType>::Native + Copy,

impl ChunkedArray<Float32Type>

This impl block contains no items.

Used to save compilation paths. Use carefully. Although this is safe, if misused it can lead to incorrect results.

impl<T> ChunkedArray<T>where T: PolarsDataType,

pub fn len(&self) -> usize

Get the length of the ChunkedArray

pub fn is_empty(&self) -> bool

Check if ChunkedArray is empty.

pub fn rechunk(&self) -> ChunkedArray<T>

pub fn slice(&self, offset: i64, length: usize) -> ChunkedArray<T>

Slice the array. The chunks are reallocated the underlying data slices are zero copy.

When offset is negative it will be counted from the end of the array. This method will never error, and will slice the best match when offset, or length is out of bounds

pub fn limit(&self, num_elements: usize) -> ChunkedArray<T>where ChunkedArray<T>: Sized,

Take a view of top n elements

pub fn head(&self, length: Option<usize>) -> ChunkedArray<T>where ChunkedArray<T>: Sized,

Get the head of the ChunkedArray

pub fn tail(&self, length: Option<usize>) -> ChunkedArray<T>where ChunkedArray<T>: Sized,

Get the tail of the ChunkedArray

impl<T> ChunkedArray<T>where T: PolarsNumericType,

pub fn extend(&mut self, other: &ChunkedArray<T>)

Extend the memory backed by this array with the values from other.

Different from ChunkedArray::append which adds chunks to this ChunkedArray extend appends the data from other to the underlying PrimitiveArray and thus may cause a reallocation.

However if this does not cause a reallocation, the resulting data structure will not have any extra chunks and thus will yield faster queries.

Prefer extend over append when you want to do a query after a single append. For instance during online operations where you add n rows and rerun a query.

Prefer append over extend when you want to append many times before doing a query. For instance when you read in multiple files and when to store them in a single DataFrame. In the latter case finish the sequence of append operations with a rechunk.

impl ChunkedArray<ListType>

pub fn amortized_iter( &self ) -> AmortizedListIter<'_, impl Iterator<Item = Option<Box<dyn Array + 'static, Global>>>>

Available on crate feature private only.

This is an iterator over a ListChunked that save allocations. A Series is: 1. Arc ChunkedArray is: 2. Vec< 3. ArrayRef>

The ArrayRef we indicated with 3. will be updated during iteration. The Series will be pinned in memory, saving an allocation for

1. Arc<..>
2. Vec<…>

Warning

Though memory safe in the sense that it will not read unowned memory, UB, or memory leaks this function still needs precautions. The returned should never be cloned or taken longer than a single iteration, as every call on next of the iterator will change the contents of that Series.
