Struct StringType

pub struct StringType {}

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 ChunkFilter<StringType> for StringChunked

fn filter( &self, filter: &BooleanChunked, ) -> PolarsResult<ChunkedArray<StringType>>

Filter values in the ChunkedArray with a boolean mask.

impl ChunkShift<StringType> for StringChunked

fn shift(&self, periods: i64) -> Self

impl ChunkShiftFill<StringType, Option<&str>> for StringChunked

fn shift_and_fill( &self, periods: i64, fill_value: Option<&str>, ) -> StringChunked

Shift the values by a given period and fill the parts that will be empty due to this operation with fill_value.

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 copy 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>
