Implementations

impl DataValue

pub fn from_string(s: &str, data_type: &DataType) -> Self

pub fn is_null(&self) -> bool

pub fn data_type(&self) -> DataType

pub fn to_string_optimized(&self) -> String

Get string representation without allocation when possible Returns owned String for compatibility but tries to reuse existing strings

Trait Implementations

impl Clone for DataValue

fn clone(&self) -> DataValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataValue

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

Formats the value using the given formatter.

impl Display for DataValue

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

Formats the value using the given formatter.

impl PartialEq for DataValue

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

Tests for self and other values to be equal, and is used by ==.

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

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