Fields

xpr: Expr

varno: Index

varattno: AttrNumber

index of this var's relation in the range table, or INNER_VAR/OUTER_VAR/INDEX_VAR

vartype: Oid

attribute number of this var, or zero for all attrs ("wholerow Var")

vartypmod: int32

pg_type OID for the type of this var

varcollid: Oid

pg_attribute typmod value

varlevelsup: Index

OID of collation, or InvalidOid if none

varnoold: Index

for subquery variables referencing outer relations; 0 in a normal var, >0 means N levels up

varoattno: AttrNumber

original value of varno, for debugging

location: c_int

original value of varattno

Trait Implementations

impl Debug for Var

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

Formats the value using the given formatter.

impl Default for Var

fn default() -> Self

Returns the "default value" for a type.

impl Eq for Var

impl Hash for Var

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<Var> for Var

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

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