Struct re_sdk::external::arrow2::scalar::Utf8Scalar

pub struct Utf8Scalar<O>
where
    O: Offset,
{
    value: Option<String>,
    phantom: PhantomData<O>,
}

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

Fields

value: Option<String>

phantom: PhantomData<O>

Implementations

impl<O> Utf8Scalar<O>

where O: Offset,

pub fn new<P>(value: Option<P>) -> Utf8Scalar<O>

where P: Into<String>,

Returns a new Utf8Scalar

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

Returns the value irrespectively of the validity.

Trait Implementations

impl<O> Clone for Utf8Scalar<O>

where O: Clone + Offset,

fn clone(&self) -> Utf8Scalar<O>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<O> Debug for Utf8Scalar<O>

where O: Debug + Offset,

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

Formats the value using the given formatter.

impl<O, P> From<Option<P>> for Utf8Scalar<O>

where O: Offset, P: Into<String>,

fn from(v: Option<P>) -> Utf8Scalar<O>

Converts to this type from the input type.

impl<O> PartialEq for Utf8Scalar<O>

where O: PartialEq + Offset,

fn eq(&self, other: &Utf8Scalar<O>) -> 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<O> Scalar for Utf8Scalar<O>

where O: Offset,

fn as_any(&self) -> &(dyn Any + 'static)

convert itself to

fn is_valid(&self) -> bool

whether it is valid

fn data_type(&self) -> &DataType

the logical type.

impl<O> Eq for Utf8Scalar<O>

where O: Eq + Offset,

impl<O> StructuralPartialEq for Utf8Scalar<O>

where O: Offset,
