Implementations

impl LiteralValue

pub fn to_anyvalue(&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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LiteralValue

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where
    __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq<LiteralValue> 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 Serialize for LiteralValue

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>where
    __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<AnyValue<'_>> for LiteralValue

type Error = PolarsError

The type returned in the event of a conversion error.

fn try_from(value: AnyValue<'_>) -> PolarsResult<Self>

Performs the conversion.

impl StructuralPartialEq for LiteralValue
