Trait Implementations

impl ChunkExpandAtIndex<StringType> for StringChunked

fn new_from_index(&self, index: usize, length: usize) -> StringChunked

Create a new ChunkedArray filled with values at that index.

impl ChunkSort<StringType> for StringChunked

fn arg_sort_multiple( &self, by: &[Column], options: &SortMultipleOptions, ) -> PolarsResult<IdxCa>

Panics

This function is very opinionated. On the implementation of ChunkedArray<T> for numeric types, we assume that all numeric Series are of the same type.

In this case we assume that all numeric Series are f64 types. The caller needs to uphold this contract. If not, it will panic.

fn sort_with(&self, options: SortOptions) -> ChunkedArray<StringType>

fn sort(&self, descending: bool) -> StringChunked

Returned a sorted ChunkedArray.

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

Retrieve the indexes needed to sort this array.

impl Clone for StringType

fn clone(&self) -> StringType

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<S> NewChunkedArray<StringType, S> for StringChunked

where S: AsRef<str>,

fn from_iter_values(name: PlSmallStr, it: impl Iterator<Item = S>) -> Self

Create a new ChunkedArray from an iterator.

fn from_slice(name: PlSmallStr, v: &[S]) -> Self

fn from_slice_options(name: PlSmallStr, opt_v: &[Option<S>]) -> Self

fn from_iter_options( name: PlSmallStr, it: impl Iterator<Item = Option<S>>, ) -> Self

Create a new ChunkedArray from an iterator.

impl NumOpsDispatchInner for StringType

fn add_to(lhs: &StringChunked, rhs: &Series) -> PolarsResult<Series>

fn subtract(lhs: &ChunkedArray<Self>, rhs: &Series) -> PolarsResult<Series>

fn multiply(lhs: &ChunkedArray<Self>, rhs: &Series) -> PolarsResult<Series>

fn divide(lhs: &ChunkedArray<Self>, rhs: &Series) -> PolarsResult<Series>

fn remainder(lhs: &ChunkedArray<Self>, rhs: &Series) -> PolarsResult<Series>

impl PolarsDataType for StringType

type Physical<'a> = &'a str

type OwnedPhysical = String

type ZeroablePhysical<'a> = Option<&'a str>

type Array = BinaryViewArrayGeneric<str>

type IsNested = FalseT

type HasViews = TrueT

type IsStruct = FalseT

type IsObject = FalseT

fn get_static_dtype() -> DataType

Returns the DataType variant associated with this PolarsDataType. Not implemented for types whose DataTypes have parameters.

impl PolarsPhysicalType for StringType

fn ca_into_series(ca: ChunkedArray<Self>) -> Series
