Implementations

impl DataValue

pub fn display_string(&self) -> String

Human-readable string for display and text-based filtering.

pub fn is_empty_value(&self) -> bool

Whether this value is considered empty for filter operators.

pub fn filter_text(&self) -> String

Case-insensitive text for Contains/StartsWith operators.

pub fn partial_cmp_typed( &self, other: &DataValue, hint: CompareHint, ) -> Option<Ordering>

Typed partial comparison for sorting. Cross-variant or invalid pairs return None.

pub fn data_type(&self) -> DataType

Infer a DataType from this value variant.
