Struct OrderByExpr 

pub struct OrderByExpr {
    pub expr: Expr,
    pub order: Option<Direction>,
}

A single expression within an OrderBy clause, with an optional sort direction.

When order is None, the database default direction is used (typically ascending).

Examples

use toasty_core::stmt::{OrderByExpr, Direction, Expr};

let expr = OrderByExpr {
    expr: Expr::null(),
    order: Some(Direction::Desc),
};

Fields

expr: Expr

The expression to order by.

order: Option<Direction>

The sort direction, or None for the database default.

Implementations

impl OrderByExpr

pub fn reverse(&mut self)

Flips the sort direction. Desc becomes default (ascending); default and Asc become Asc (explicit ascending, since the default changed).

Trait Implementations

impl Clone for OrderByExpr

fn clone(&self) -> OrderByExpr

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OrderByExpr

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl From<OrderByExpr> for OrderBy

fn from(value: OrderByExpr) -> OrderBy

Converts to this type from the input type.

impl PartialEq for OrderByExpr

fn eq(&self, other: &OrderByExpr) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
