Trait Implementations

impl Clone for BinaryExpr

fn clone(&self) -> BinaryExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BinaryExpr

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

Formats the value using the given formatter.

impl Display for BinaryExpr

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

Formats the value using the given formatter.

impl ExprTrait for BinaryExpr

fn data_type(&self, input_schema: &Schema) -> QuillSQLResult<DataType>

Get the data type of this expression, given the schema of the input

fn nullable(&self, input_schema: &Schema) -> QuillSQLResult<bool>

Determine whether this expression is nullable, given the schema of the input

fn evaluate(&self, tuple: &Tuple) -> QuillSQLResult<ScalarValue>

Evaluate an expression against a Tuple

fn to_column(&self, input_schema: &Schema) -> QuillSQLResult<Column>

convert to a column with respect to a schema

impl PartialEq for BinaryExpr

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