Struct AliasedResultExpr

pub struct AliasedResultExpr {
    pub expr: Box<Expression>,
    pub alias: Identifier,
}

An expression with an alias e.g. a + 1 AS b

Fields

expr: Box<Expression>

The expression e.g. a + 1, COUNT(*), etc.

alias: Identifier

The alias e.g. count in COUNT(*) AS count

Implementations

impl AliasedResultExpr

pub fn new(expr: Expression, alias: Identifier) -> Self

Create a new AliasedResultExpr

pub fn try_as_identifier(&self) -> Option<&Identifier>

Try to get the identifier of the expression if it is a column Otherwise return None

Trait Implementations

impl Clone for AliasedResultExpr

fn clone(&self) -> AliasedResultExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AliasedResultExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AliasedResultExpr

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<AliasedResultExpr> for SelectResultExpr

fn from(value: AliasedResultExpr) -> Self

Converts to this type from the input type.

impl PartialEq for AliasedResultExpr

fn eq(&self, other: &AliasedResultExpr) -> 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 Serialize for AliasedResultExpr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
