Enum UserDefinedTypeRangeOption 

pub enum UserDefinedTypeRangeOption {
    Subtype(DataType),
    SubtypeOpClass(ObjectName),
    Collation(ObjectName),
    Canonical(ObjectName),
    SubtypeDiff(ObjectName),
    MultirangeTypeName(ObjectName),
}

Options for PostgreSQL CREATE TYPE ... AS RANGE statement.

Range types are data types representing a range of values of some element type (called the range’s subtype). These options configure the behavior of the range type.

PostgreSQL Documentation

See: https://www.postgresql.org/docs/current/sql-createtype.html

Examples

CREATE TYPE int4range AS RANGE (
    SUBTYPE = int4,
    SUBTYPE_OPCLASS = int4_ops,
    CANONICAL = int4range_canonical,
    SUBTYPE_DIFF = int4range_subdiff
);

Variants

Subtype(DataType)

The element type that the range type will represent: SUBTYPE = subtype

SubtypeOpClass(ObjectName)

The operator class for the subtype: SUBTYPE_OPCLASS = subtype_operator_class

Collation(ObjectName)

Collation to use for ordering the subtype: COLLATION = collation

Canonical(ObjectName)

Function to convert range values to canonical form: CANONICAL = canonical_function

SubtypeDiff(ObjectName)

Function to compute the difference between two subtype values: SUBTYPE_DIFF = subtype_diff_function

MultirangeTypeName(ObjectName)

Name of the corresponding multirange type: MULTIRANGE_TYPE_NAME = multirange_type_name

Trait Implementations

impl Clone for UserDefinedTypeRangeOption

fn clone(&self) -> UserDefinedTypeRangeOption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UserDefinedTypeRangeOption

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

Formats the value using the given formatter.

impl Display for UserDefinedTypeRangeOption

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

Formats the value using the given formatter.

impl Hash for UserDefinedTypeRangeOption

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

where __H: Hasher,

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 Ord for UserDefinedTypeRangeOption

fn cmp(&self, other: &UserDefinedTypeRangeOption) -> 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,

Restrict a value to a certain interval.

impl PartialEq for UserDefinedTypeRangeOption

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for UserDefinedTypeRangeOption

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Visit for UserDefinedTypeRangeOption

fn visit<V>(&self, visitor: &mut V) -> ControlFlow<<V as Visitor>::Break>

where V: Visitor,

Visit this node with the provided Visitor.

impl VisitMut for UserDefinedTypeRangeOption

fn visit<V>(&mut self, visitor: &mut V) -> ControlFlow<<V as VisitorMut>::Break>

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.
