Enum query_builder::OrderBy
[−]
[src]
pub enum OrderBy<'b> { Row(&'b str), Expression(&'b str), }
Representing the way to format the ORDER BY clause of some queries
Variants
Row(&'b str)
Expression(&'b str)
Methods
impl<'b> OrderBy<'b>
[src]
pub fn as_string(&self) -> String
[src]
Display the OrderBy
clause as a String
Currently it doesen't matter if you used OrderBy::Row
or
OrderBy::Expression
as both result in the exat same String
though
this might change in the future
