Struct TableAliasColumnDef 

pub struct TableAliasColumnDef {
    pub name: Ident,
    pub data_type: Option<DataType>,
}

SQL column definition in a table expression alias. Most of the time, the data type is not specified. But some table-valued functions do require specifying the data type.

See https://www.postgresql.org/docs/17/queries-table-expressions.html#QUERIES-TABLEFUNCTIONS

Fields

name: Ident

Column name alias

data_type: Option<DataType>

Some table-valued functions require specifying the data type in the alias.

Implementations

impl TableAliasColumnDef

pub fn from_name<S>(name: S) -> TableAliasColumnDef

where S: Into<String>,

Create a new table alias column definition with only a name and no type

Trait Implementations

impl Clone for TableAliasColumnDef

fn clone(&self) -> TableAliasColumnDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TableAliasColumnDef

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

Formats the value using the given formatter.

impl Display for TableAliasColumnDef

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

Formats the value using the given formatter.

impl Hash for TableAliasColumnDef

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 TableAliasColumnDef

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

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

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

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 Eq for TableAliasColumnDef
