Struct ReturnItem 

pub struct ReturnItem {
    pub expr: Expr,
    pub alias: Option<String>,
    pub display: Option<String>,
    pub span: Span,
}

A single item in a RETURN or WITH projection.

Fields

expr: Expr

alias: Option<String>

Optional AS alias name.

display: Option<String>

The verbatim source text of expr (no AS part), captured by the parser for an un-aliased item. openCypher names an un-aliased projection column by the expression as written (n.prop, count(*), a.x IS NULL); the binder uses this as the default RETURN column name when there is no alias. None for RETURN * and for items built outside the parser.

span: Span
