Trait Orderable

pub trait Orderable<'a>
where
    Self: Sized,
{
    // Required method
    fn order(self, order: Option<Order>) -> OrderDefinition<'a>;

    // Provided methods
    fn ascend(self) -> OrderDefinition<'a> { ... }

An item that can be used in the ORDER BY statement

Required Methods

fn order(self, order: Option<Order>) -> OrderDefinition<'a>

Order by self in the given order

Provided Methods

fn ascend(self) -> OrderDefinition<'a>

Change the order to ASC

fn descend(self) -> OrderDefinition<'a>

Change the order to DESC

fn ascend_nulls_first(self) -> OrderDefinition<'a>

Change the order to ASC NULLS FIRST

fn ascend_nulls_last(self) -> OrderDefinition<'a>

Change the order to ASC NULLS LAST

fn descend_nulls_first(self) -> OrderDefinition<'a>

Change the order to DESC NULLS FIRST

fn descend_nulls_last(self) -> OrderDefinition<'a>

Change the order to ASC NULLS LAST

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
