Struct polars_arrow::scalar::BinaryViewScalar

pub struct BinaryViewScalar<T: ViewType + ?Sized> { /* private fields */ }

The implementation of Scalar for utf8, semantically equivalent to Option<String>.

Implementations

impl<T: ViewType + ?Sized> BinaryViewScalar<T>

pub fn new(value: Option<&T>) -> Self

Returns a new BinaryViewScalar

pub fn value(&self) -> Option<&T>

Returns the value irrespectively of the validity.

Trait Implementations

impl<T: ViewType + ?Sized> Clone for BinaryViewScalar<T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: ViewType + ?Sized> Debug for BinaryViewScalar<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T: ViewType + ?Sized> From<Option<&T>> for BinaryViewScalar<T>

fn from(v: Option<&T>) -> Self

Converts to this type from the input type.

impl<T: PartialEq + ViewType + ?Sized> PartialEq for BinaryViewScalar<T>

where T::Owned: PartialEq,

fn eq(&self, other: &BinaryViewScalar<T>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<T: ViewType + ?Sized> Scalar for BinaryViewScalar<T>

fn as_any(&self) -> &dyn Any

convert itself to

fn is_valid(&self) -> bool

whether it is valid

fn data_type(&self) -> &ArrowDataType

the logical type.
