Enum arrow_udf_python::CallMode

pub enum CallMode {
    CalledOnNullInput,
    ReturnNullOnNullInput,
}

Whether the function will be called when some of its arguments are null.

Variants

CalledOnNullInput

The function will be called normally when some of its arguments are null. It is then the function author’s responsibility to check for null values if necessary and respond appropriately.

ReturnNullOnNullInput

The function always returns null whenever any of its arguments are null. If this parameter is specified, the function is not executed when there are null arguments; instead a null result is assumed automatically.

Trait Implementations

impl Debug for CallMode

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

Formats the value using the given formatter.

impl Default for CallMode

fn default() -> CallMode

Returns the “default value” for a type.

impl Ord for CallMode

fn cmp(&self, other: &CallMode) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for CallMode

fn eq(&self, other: &CallMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for CallMode

fn partial_cmp(&self, other: &CallMode) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
