Struct prql_compiler::ast::expr::Expr

pub struct Expr {
    pub kind: ExprKind,
    pub span: Option<Span>,
    pub alias: Option<String>,
}

Expr is anything that has a value and thus a type. Most of these can contain other Expr themselves; literals should be ExprKind::Literal.

Fields

kind: ExprKind

span: Option<Span>

alias: Option<String>

Implementations

impl Expr

pub fn new<K>(kind: K) -> Expr

where K: Into<ExprKind>,

Trait Implementations

impl Clone for Expr

fn clone(&self) -> Expr

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Expr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Expr

fn deserialize<__D>( __deserializer: __D, ) -> Result<Expr, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Expr

fn eq(&self, other: &Expr) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Expr

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
