Struct datafusion_physical_expr::intervals::interval_aritmetic::IntervalBound

pub struct IntervalBound {
    pub value: ScalarValue,
    pub open: bool,
}

This type represents a single endpoint of an Interval. An endpoint can be open or closed, denoting whether the interval includes or excludes the endpoint itself.

Fields

value: ScalarValue

open: bool

Implementations

impl IntervalBound

pub const fn new(value: ScalarValue, open: bool) -> IntervalBound

Creates a new IntervalBound object using the given value.

pub fn make_unbounded<T: Borrow<DataType>>(data_type: T) -> Result<Self>

This convenience function creates an unbounded interval endpoint.

pub fn get_datatype(&self) -> DataType

This convenience function returns the data type associated with this IntervalBound.

pub fn is_unbounded(&self) -> bool

This convenience function checks whether the IntervalBound represents an unbounded interval endpoint.

pub fn add<const UPPER: bool, T: Borrow<IntervalBound>>( &self, other: T ) -> Result<IntervalBound>

This function adds the given IntervalBound to this IntervalBound. The result is unbounded if either is; otherwise, their values are added. The result is closed if both original bounds are closed, or open otherwise.

pub fn sub<const UPPER: bool, T: Borrow<IntervalBound>>( &self, other: T ) -> Result<IntervalBound>

This function subtracts the given IntervalBound from self. The result is unbounded if either is; otherwise, their values are subtracted. The result is closed if both original bounds are closed, or open otherwise.

pub fn choose( first: &IntervalBound, second: &IntervalBound, decide: fn(_: &ScalarValue, _: &ScalarValue) -> Result<ScalarValue> ) -> Result<IntervalBound>

This function chooses one of the given IntervalBounds according to the given function decide. The result is unbounded if both are. If only one of the arguments is unbounded, the other one is chosen by default. If neither is unbounded, the function decide is used.

Trait Implementations

impl Clone for IntervalBound

fn clone(&self) -> IntervalBound

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for IntervalBound

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

Formats the value using the given formatter.

impl Display for IntervalBound

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

Formats the value using the given formatter.

impl PartialEq<IntervalBound> for IntervalBound

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