Implementations

impl BinaryFunc

pub fn eval<'a>(
    &'a self,
    datums: &[Datum<'a>],
    temp_storage: &'a RowArena,
    a_expr: &'a MirScalarExpr,
    b_expr: &'a MirScalarExpr
) -> Result<Datum<'a>, EvalError>

pub fn output_type(
    &self,
    input1_type: ColumnType,
    input2_type: ColumnType
) -> ColumnType

pub fn propagates_nulls(&self) -> bool

Whether the function output is NULL if any of its inputs are NULL.

pub fn introduces_nulls(&self) -> bool

Whether the function might return NULL even if none of its inputs are NULL.

This is presently conservative, and may indicate that a function introduces nulls even when it does not.

pub fn is_infix_op(&self) -> bool

pub fn negate(&self) -> Option<Self>

Returns the negation of the given binary function, if it exists.
