Enum PartitionBoundValue 

pub enum PartitionBoundValue {
    Expr(Expr),
    MinValue,
    MaxValue,
}

A value in a partition bound specification.

Used in RANGE partition bounds where values can be expressions, MINVALUE (negative infinity), or MAXVALUE (positive infinity).

Variants

Expr(Expr)

An expression representing a partition bound value.

MinValue

Represents negative infinity in partition bounds.

MaxValue

Represents positive infinity in partition bounds.

Trait Implementations

impl Clone for PartitionBoundValue

fn clone(&self) -> PartitionBoundValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionBoundValue

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

Formats the value using the given formatter.

impl Display for PartitionBoundValue

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

Formats the value using the given formatter.

impl Eq for PartitionBoundValue

impl Hash for PartitionBoundValue

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 PartitionBoundValue

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

fn eq(&self, other: &PartitionBoundValue) -> 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 PartitionBoundValue

fn partial_cmp(&self, other: &PartitionBoundValue) -> 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 Spanned for PartitionBoundValue

fn span(&self) -> Span

Return the Span (the minimum and maximum Location) for this AST node, by recursively combining the spans of its children.

impl StructuralPartialEq for PartitionBoundValue

impl Visit for PartitionBoundValue

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 PartitionBoundValue

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

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.
