Implementations

impl LiteralValue

pub fn to_any_value(&self) -> Option<AnyValue<'_>>

pub fn get_datatype(&self) -> DataType

Getter for the DataType of the value

Trait Implementations

impl Clone for LiteralValue

fn clone(&self) -> LiteralValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LiteralValue

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

Formats the value using the given formatter.

impl Hash for LiteralValue

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Literal for LiteralValue

fn lit(self) -> Expr

Literal expression.

impl PartialEq for LiteralValue

fn eq(&self, other: &LiteralValue) -> 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 TryFrom<AnyValue<'_>> for LiteralValue

type Error = PolarsError

The type returned in the event of a conversion error.

fn try_from(value: AnyValue<'_>) -> Result<LiteralValue, PolarsError>

Performs the conversion.
