Ordered

Struct Ordered 

Source
pub struct Ordered<'a, V: SQLParam, S> { /* private fields */ }
Expand description

One ORDER BY term, such as "users"."age" DESC; created by asc or desc.

S records the tables the term reads, for the query’s scope check. To order by several columns, pass a tuple of terms: order_by((asc(a), desc(b))). An array or Vec also works when every term has the same type.
