Struct postgres_parser::sys::IndexElem

#[repr(C)]pub struct IndexElem {
    pub type_: NodeTag,
    pub name: *mut c_char,

IndexElem index parameters (used in CREATE INDEX, and in ON CONFLICT)

For a plain index attribute, 'name' is the name of the table column to index, and 'expr' is NULL. For an index expression, 'name' is NULL and 'expr' is the expression tree.

Fields

type_: NodeTag

name: *mut c_char

expr: *mut Node

name of attribute to index, or NULL

indexcolname: *mut c_char

expression to index, or NULL

collation: *mut List

name for index column; NULL = default

opclass: *mut List

name of collation; NIL = default

ordering: SortByDir

name of desired opclass; NIL = default

nulls_ordering: SortByNulls
