Function reverse 

pub fn reverse<'a, V, E>(
    expr: E,
) -> SQLExpr<'a, V, <V::DialectMarker as DialectTypes>::Text, E::Nullable, E::Aggregate, E::Sources>
where
    V: SQLParam + 'a,
    V::DialectMarker: DialectSupports<Reverse>,
    E: Expr<'a, V>,
    E::SQLType: Textual,

Reverses a text value (REVERSE), on PostgreSQL and MySQL.

The argument must be text. The result is text and keeps the argument’s nullability.

Examples

assert_eq!(reverse(users.name).sql(), r#"REVERSE ("users"."name")"#);
