An operator, one row of pg_operator.

Fields

oid: u32

The OID. Catalog::create_operator sets it.

name: String

The name.

namespace: u32

The OID of the schema.

owner: u32

The OID of the owner role.

kind: u8

oprkind: b for an infix operator or l for a prefix operator.

can_merge: bool

oprcanmerge.

can_hash: bool

oprcanhash.

left: u32

oprleft: the type of the left input, or 0 for a prefix operator.

right: u32

oprright.

result: u32

oprresult, or 0 for a shell.

commutator: u32

oprcom: the commutator, or 0.

negator: u32

oprnegate: the negator, or 0.

code: u32

oprcode: the function, or 0 for a shell.

restrict: u32

oprrest: the restriction estimator, or 0.

join: u32

oprjoin: the join estimator, or 0.

Implementations

impl Operator

pub fn shell( name: &str, namespace: u32, owner: u32, left: u32, right: u32, ) -> Operator

OperatorShellMake: an operator with a name and input types only, which a later CREATE OPERATOR fills.

Trait Implementations

impl Clone for Operator

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operator

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

Formats the value using the given formatter.

impl Eq for Operator

impl PartialEq for Operator

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

Equality operator ==.

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

Inequality operator !=.
