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<BinaryFunc>

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

pub fn could_error(&self) -> bool

Returns true if the function could introduce an error on non-error inputs.

pub fn is_monotone(&self) -> (bool, bool)

Returns true if the function is monotone. (Non-strict; either increasing or decreasing.) Monotone functions map ranges to ranges: ie. given a range of possible inputs, we can determine the range of possible outputs just by mapping the endpoints.

This describes the pointwise behaviour of the function: ie. the behaviour of any specific argument as the others are held constant. (For example, a - b is monotone in the first argument because for any particular value of b, increasing a will always cause the result to increase… and in the second argument because for any specific a, increasing b will always cause the result to decrease.)

This property describes the behaviour of the function over ranges where the function is defined: ie. the arguments and the result are non-error datums.
