Struct OrderBy 

pub struct OrderBy {
    pub expressions: Vec<Expr>,
}

ORDER BY a, b DESC

Fields

expressions: Vec<Expr>

The sort keys, in precedence order. Usually OrderDefs, but a bare expression is a sort key too.

Implementations

impl OrderBy

pub fn append_order(&mut self, order: impl IntoExpr)

Append one sort key.

pub fn clear_order_by(&mut self)

Drop every sort key. Needed because a mod may have to replace an inherited ordering rather than add to it.

pub fn is_empty(&self) -> bool

Whether the clause is absent.
