Methods

impl ScalarValue

pub fn get_datatype(&self) -> DataType

Getter for the DataType of the value

Trait Implementations

impl PartialEq<ScalarValue> for ScalarValue

fn eq(&self, other: &ScalarValue) -> bool

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

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

This method tests for !=.

impl Clone for ScalarValue

fn clone(&self) -> ScalarValue

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScalarValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ScalarValue

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

Deserialize this value from the given Serde deserializer.

impl Serialize for ScalarValue

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

Serialize this value into the given Serde serializer.
