Trait Implementations

impl ChunkQuantile<f64> for Float64Chunked

fn quantile(
    &self,
    quantile: f64,
    interpol: QuantileInterpolOptions
) -> PolarsResult<Option<f64>>

Aggregate a given quantile of the ChunkedArray. Returns None if the array is empty or only contains null values.

fn median(&self) -> Option<f64>

Returns the mean value in the array. Returns None if the array is empty or only contains null values.

impl ChunkSort<Float64Type> for Float64Chunked

fn argsort_multiple(
    &self,
    other: &[Series],
    reverse: &[bool]
) -> PolarsResult<IdxCa>

Panics

This function is very opinionated. We assume that all numeric Series are of the same type, if not it will panic

fn sort_with(&self, options: SortOptions) -> Float64Chunked

fn sort(&self, reverse: bool) -> Float64Chunked

Returned a sorted ChunkedArray.

fn argsort(&self, options: SortOptions) -> IdxCa

Retrieve the indexes needed to sort this array.

impl ChunkUnique<Float64Type> for Float64Chunked

fn unique(&self) -> PolarsResult<ChunkedArray<Float64Type>>

Get unique values of a ChunkedArray

fn arg_unique(&self) -> PolarsResult<IdxCa>

Get first index of the unique values in a ChunkedArray. This Vec is sorted.

fn is_unique(&self) -> PolarsResult<BooleanChunked>

Get a mask of all the unique values.

fn is_duplicated(&self) -> PolarsResult<BooleanChunked>

Get a mask of all the duplicated values.

fn n_unique(&self) -> PolarsResult<usize>

Number of unique values in the ChunkedArray

fn mode(&self) -> PolarsResult<ChunkedArray<T>>

Available on crate feature mode only.

The most occurring value(s). Can return multiple Values

impl ChunkVar<f64> for Float64Chunked

fn var(&self, ddof: u8) -> Option<f64>

Compute the variance of this ChunkedArray/Series.

fn std(&self, ddof: u8) -> Option<f64>

Compute the standard deviation of this ChunkedArray/Series.

impl NumOpsDispatchChecked for Float64Chunked

Available on crate feature checked_arithmetic only.

fn checked_div(&self, rhs: &Series) -> PolarsResult<Series>

Checked integer division. Computes self / rhs, returning None if rhs == 0 or the division results in overflow.

fn checked_div_num<T: ToPrimitive>(&self, _rhs: T) -> PolarsResult<Series>

impl QuantileAggSeries for Float64Chunked

fn quantile_as_series(
    &self,
    quantile: f64,
    interpol: QuantileInterpolOptions
) -> PolarsResult<Series>

Get the quantile of the ChunkedArray as a new Series of length 1.

fn median_as_series(&self) -> Series

Get the median of the ChunkedArray as a new Series of length 1.

impl VarAggSeries for Float64Chunked

fn var_as_series(&self, ddof: u8) -> Series

Get the variance of the ChunkedArray as a new Series of length 1.

fn std_as_series(&self, ddof: u8) -> Series

Get the standard deviation of the ChunkedArray as a new Series of length 1.

impl VecHash for Float64Chunked

fn vec_hash(&self, random_state: RandomState, buf: &mut Vec<u64>)

Compute the hash for all values in the array.

fn vec_hash_combine(&self, random_state: RandomState, hashes: &mut [u64])

impl ZipOuterJoinColumn for Float64Chunked
