Struct postgres_parser::sys::Expr

#[repr(C)]pub struct Expr {
    pub type_: NodeTag,
}

Expr generic superclass for executableexpression nodes

All node types that are used in executable expression trees should derive from Expr (that is, have Expr as their first field). Since Expr only contains NodeTag, this is a formality, but it is an easy form of documentation. See also the ExprState node types in execnodes.h.

Fields

type_: NodeTag

Trait Implementations

impl Debug for Expr

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

Formats the value using the given formatter.

impl Default for Expr

fn default() -> Self

Returns the "default value" for a type.

impl Eq for Expr

impl Hash for Expr

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl PartialEq<Expr> 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: &Expr) -> bool

This method tests for !=.
