Enum XmlTableColumnOption 

pub enum XmlTableColumnOption {
    NamedInfo {
        type: DataType,
        path: Option<Expr>,
        default: Option<Expr>,
        nullable: bool,
    },
    ForOrdinality,
}

Defines the options for an XmlTable column: Named or ForOrdinality

Variants

NamedInfo

A named column with a type, optional path, and default value.

Fields

type: DataType

The type of the column to be extracted.

path: Option<Expr>

The path to the column to be extracted. If None, defaults to the column name.

default: Option<Expr>

Default value if path does not match

nullable: bool

Whether the column is nullable (NULL=true, NOT NULL=false)

ForOrdinality

The FOR ORDINALITY marker

Trait Implementations

impl Clone for XmlTableColumnOption

fn clone(&self) -> XmlTableColumnOption

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for XmlTableColumnOption

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

Formats the value using the given formatter.

impl Hash for XmlTableColumnOption

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 XmlTableColumnOption

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

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

fn partial_cmp(&self, other: &XmlTableColumnOption) -> 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 XmlTableColumnOption

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

where V: Visitor,

impl VisitMut for XmlTableColumnOption

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

where V: VisitorMut,
