Struct postgres_parser::sys::InferenceElem

#[repr(C)]pub struct InferenceElem {
    pub xpr: Expr,
    pub expr: *mut Node,
    pub infercollid: Oid,
    pub inferopclass: Oid,
}

InferenceElem an element of a unique index inference specification

This mostly matches the structure of IndexElems, but having a dedicated primnode allows for a clean separation between the use of index parameters by utility commands, and this node.

Fields

xpr: Expr

expr: *mut Node

infercollid: Oid

expression to infer from, or NULL

inferopclass: Oid

OID of collation, or InvalidOid
