Struct postgres_parser::nodes::IndexElem

pub struct IndexElem {
    pub name: Option<String>,
    pub expr: Option<Box<Node>>,
    pub indexcolname: Option<String>,
    pub collation: Option<Vec<Node>>,
    pub opclass: Option<Vec<Node>>,
    pub ordering: SortByDir,
    pub nulls_ordering: SortByNulls,
}

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

name: Option<String>

expr: Option<Box<Node>>

indexcolname: Option<String>

collation: Option<Vec<Node>>

opclass: Option<Vec<Node>>

ordering: SortByDir

nulls_ordering: SortByNulls
