Struct NumericProjectionExpr 

pub struct NumericProjectionExpr { /* private fields */ }

NumericProjectionExpr

Shared bounded numeric projection over one source field and one numeric literal. This stays on the narrow field op literal seam admitted by the shipped SQL and fluent scalar projection surfaces.

Trait Implementations

impl Clone for NumericProjectionExpr

fn clone(&self) -> NumericProjectionExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumericProjectionExpr

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

Formats the value using the given formatter.

impl PartialEq for NumericProjectionExpr

fn eq(&self, other: &NumericProjectionExpr) -> 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.

impl ValueProjectionExpr for NumericProjectionExpr

fn field(&self) -> &str

Borrow the single source field used by this bounded helper.

fn sql_label(&self) -> String

Render the stable SQL-style output label for this projection.

fn apply_value(&self, value: Value) -> Result<Value, QueryError>

Apply this projection to one already-loaded source value.
