pub struct Series(pub Arc<dyn SeriesTrait>);
Expand description
§Series
The columnar data type for a DataFrame.
Most of the available functions are defined in the SeriesTrait trait.
The Series
struct consists
of typed ChunkedArray’s. To quickly cast
a Series
to a ChunkedArray
you can call the method with the name of the type:
let s: Series = [1, 2, 3].iter().collect();
// Quickly obtain the ChunkedArray wrapped by the Series.
let chunked_array = s.i32().unwrap();
§Arithmetic
You can do standard arithmetic on series.
let s = Series::new("a".into(), [1 , 2, 3]);
let out_add = &s + &s;
let out_sub = &s - &s;
let out_div = &s / &s;
let out_mul = &s * &s;
Or with series and numbers.
let s: Series = (1..3).collect();
let out_add_one = &s + 1;
let out_multiply = &s * 10;
// Could not overload left hand side operator.
let out_divide = 1.div(&s);
let out_add = 1.add(&s);
let out_subtract = 1.sub(&s);
let out_multiply = 1.mul(&s);
§Comparison
You can obtain boolean mask by comparing series.
let s = Series::new("dollars".into(), &[1, 2, 3]);
let mask = s.equal(1).unwrap();
let valid = [true, false, false].iter();
assert!(mask
.into_iter()
.map(|opt_bool| opt_bool.unwrap()) // option, because series can be null
.zip(valid)
.all(|(a, b)| a == *b))
See all the comparison operators in the ChunkCompareEq trait and ChunkCompareIneq trait.
§Iterators
The Series variants contain differently typed ChunkedArrays. These structs can be turned into iterators, making it possible to use any function/ closure you want on a Series.
These iterators return an Option<T>
because the values of a series may be null.
use polars_core::prelude::*;
let pi = 3.14;
let s = Series::new("angle".into(), [2f32 * pi, pi, 1.5 * pi].as_ref());
let s_cos: Series = s.f32()
.expect("series was not an f32 dtype")
.into_iter()
.map(|opt_angle| opt_angle.map(|angle| angle.cos()))
.collect();
§Creation
Series can be create from different data structures. Below we’ll show a few ways we can create a Series object.
// Series can be created from Vec's, slices and arrays
Series::new("boolean series".into(), &[true, false, true]);
Series::new("int series".into(), &[1, 2, 3]);
// And can be nullable
Series::new("got nulls".into(), &[Some(1), None, Some(2)]);
// Series can also be collected from iterators
let from_iter: Series = (0..10)
.into_iter()
.collect();

Implementations§
Source§impl Series
impl Series
Sourcepub fn fill_null(&self, strategy: FillNullStrategy) -> PolarsResult<Series>
pub fn fill_null(&self, strategy: FillNullStrategy) -> PolarsResult<Series>
Replace None values with one of the following strategies:
- Forward fill (replace None with the previous value)
- Backward fill (replace None with the next value)
- Mean fill (replace None with the mean of the whole array)
- Min fill (replace None with the minimum of the whole array)
- Max fill (replace None with the maximum of the whole array)
- Zero fill (replace None with the value zero)
- One fill (replace None with the value one)
- MinBound fill (replace with the minimum of that data type)
- MaxBound fill (replace with the maximum of that data type)
NOTE: If you want to fill the Nones with a value use the
fill_null
operation on ChunkedArray<T>
.
§Example
fn example() -> PolarsResult<()> {
let s = Column::new("some_missing".into(), &[Some(1), None, Some(2)]);
let filled = s.fill_null(FillNullStrategy::Forward(None))?;
assert_eq!(Vec::from(filled.i32()?), &[Some(1), Some(1), Some(2)]);
let filled = s.fill_null(FillNullStrategy::Backward(None))?;
assert_eq!(Vec::from(filled.i32()?), &[Some(1), Some(2), Some(2)]);
let filled = s.fill_null(FillNullStrategy::Min)?;

let filled = s.fill_null(FillNullStrategy::Zero)?;

let filled = s.fill_null(FillNullStrategy::One)?;

let filled = s.fill_null(FillNullStrategy::MinBound)?;
assert_eq!(Vec::from(filled.i32()?), &[Some(1), Some(-2147483648), Some(2)]);
let filled = s.fill_null(FillNullStrategy::MaxBound)?;
assert_eq!(Vec::from(filled.i32()?), &[Some(1), Some(2147483647), Some(2)]);

pub fn from_any_values( name: PlSmallStr, values: &[AnyValue<'_>], strict: bool, ) -> PolarsResult<Self>
Construct a new Series
from a slice of AnyValues.
The data type of the resulting Series is determined by the values
and the strict
parameter:
- If
strict
istrue
, the data type is equal to the data type of the first non-null value. If any other non-null values do not match this data type, an error is raised. - If
strict
isfalse
, the data type is the supertype of thevalues
. An error is returned if no supertype can be determined. WARNING: A full pass over the values is required to determine the supertype. - If no values were passed, the resulting data type is
Null
.

Construct a new Series

from a slice of AnyValues.
If strict
is true
, an error is returned if the values do not match the given
data type. If strict
is false
, values that do not match the given data type
are cast. If casting is not possible, the values are set to null instead.

Attempts to convert a Series to dtype, only allowing conversions from physical to logical dtypes–the inverse of to_physical_repr().
§Safety
When converting from UInt32 to Categorical it is not checked that the values are in-bound for the categorical mapping.
Sourcepub fn gather_every(&self, n: usize, offset: usize) -> Series
pub fn gather_every(&self, n: usize, offset: usize) -> Series
Traverse and collect every nth element in a new array.
pub fn dot(&self, other: &Series) -> PolarsResult<f64>
dot_product
only.Sourcepub fn sum_reduce(&self) -> PolarsResult<Scalar>
pub fn sum_reduce(&self) -> PolarsResult<Scalar>
Get the sum of the Series as a new Series of length 1. Returns a Series with a single zeroed entry if self is an empty numeric series.
If the DataType
is one of {Int8, UInt8, Int16, UInt16}
the Series
is
first cast to Int64
to prevent overflow issues.
Sourcepub fn product(&self) -> PolarsResult<Scalar>
pub fn product(&self) -> PolarsResult<Scalar>
Get the product of an array.
If the DataType
is one of {Int8, UInt8, Int16, UInt16}
the Series
is
first cast to Int64
to prevent overflow issues.
Sourcepub fn strict_cast(&self, dtype: &DataType) -> PolarsResult<Series>
pub fn strict_cast(&self, dtype: &DataType) -> PolarsResult<Series>
Cast throws an error if conversion had overflows
pub fn str_value(&self, index: usize) -> PolarsResult<Cow<'_, str>>
pub fn mean_reduce(&self) -> Scalar
Sourcepub fn unique_stable(&self) -> PolarsResult<Series>
pub fn unique_stable(&self) -> PolarsResult<Series>
Compute the unique elements, but maintain order. This requires more work
than a naive Series::unique
.
pub fn try_idx(&self) -> Option<&IdxCa>
pub fn idx(&self) -> PolarsResult<&IdxCa>
Sourcepub fn estimated_size(&self) -> usize
pub fn estimated_size(&self) -> usize
Returns an estimation of the total (heap) allocated size of the Series
in bytes.
§Implementation
This estimation is the sum of the size of its buffers, validity, including nested arrays.
Multiple arrays may share buffers and bitmaps. Therefore, the size of 2 arrays is not the
sum of the sizes computed from this function. In particular, [StructArray
]’s size is an upper bound.
When an array is sliced, its allocated size remains constant because the buffer unchanged. However, this function will yield a smaller number. This is because this function returns the visible size of the buffer, not its total capacity.
FFI buffers are included in this estimation.
Sourcepub fn as_list(&self) -> ListChunked
pub fn as_list(&self) -> ListChunked
Packs every element into a list.
