Struct ViewColumnDef 

pub struct ViewColumnDef {
    pub name: Ident,
    pub data_type: Option<DataType>,
    pub options: Option<ColumnOptions>,
}

Column definition specified in a CREATE VIEW statement.

Syntax

<name> [data_type][OPTIONS(option, ...)]

option: <name> = <value>

Examples:

name
age OPTIONS(description = "age column", tag = "prod")
amount COMMENT 'The total amount for the order line'
created_at DateTime64

Fields

name: Ident

Column identifier.

data_type: Option<DataType>

Optional data type for the column.

options: Option<ColumnOptions>

Optional column options (defaults, comments, etc.).

Trait Implementations

impl Clone for ViewColumnDef

fn clone(&self) -> ViewColumnDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ViewColumnDef

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

Formats the value using the given formatter.

impl Display for ViewColumnDef

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

Formats the value using the given formatter.

impl Eq for ViewColumnDef

impl Hash for ViewColumnDef

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 ViewColumnDef

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

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

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

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 ViewColumnDef

impl Visit for ViewColumnDef

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 ViewColumnDef

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

where V: VisitorMut,

Mutably visit this node with the provided VisitorMut.
