Enum pgrx::datum::RangeBound

pub enum RangeBound<T> {
    Infinite,
    Inclusive(T),
    Exclusive(T),
}

A Postgres Range’s “lower” or “upper” value

Variants

Infinite

Inclusive(T)

Exclusive(T)

Implementations

impl<T> RangeBound<T>where T: RangeSubType,

pub fn get(&self) -> Option<&T>

Returns a reference to this RangeBound’s underlying value.

If this RangeBound is RangeBound::Infinite, then None is returned, otherwise Some(&T)

pub fn is_infinite(&self) -> bool

Returns true if this RangeBound represents the Infinite variant

pub fn is_inclusive(&self) -> bool

Returns true if this RangeBound represents the Inclusive variant

pub fn is_exclusive(&self) -> bool

Returns true if this RangeBound represents the Exclusive variant

pub unsafe fn from_pg(range_bound: RangeBound) -> RangeBound<T>

Create a typed pgrx RangeBound from an arbitrary Postgres pg_sys::RangeBound.

Safety

This function is unsafe as it cannot guarantee that the val property, which is a pg_sys::Datum, points to (or is) something correct for the generic type T.

Trait Implementations

impl<T: Clone> Clone for RangeBound<T>

fn clone(&self) -> RangeBound<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for RangeBound<T>

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

Formats the value using the given formatter.

impl<T> From<Option<T>> for RangeBound<T>where T: RangeSubType,

fn from(value: Option<T>) -> Self

Conversion of an Option to a RangeBound.

Some maps to the RangeBound::Inclusive variant and None maps to the [RangeBound::infinite] value.

impl<T> From<T> for RangeBound<T>where T: RangeSubType,

fn from(value: T) -> Self

Converts to this type from the input type.

impl<T: Hash> Hash for RangeBound<T>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<T: PartialEq> PartialEq<RangeBound<T>> for RangeBound<T>

fn eq(&self, other: &RangeBound<T>) -> 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.
