Enum json_api::query::Direction

pub enum Direction {
    Asc,
    Desc,
}

The direction of a sort instruction.

Variants

Asc

Ascending

Desc

Descending

Methods

impl Direction

fn is_asc(&self) -> bool

Returns true if the direction is Asc.

Example

use json_api::query::Direction;

let direction = Direction::Desc;
assert_eq!(direction.is_asc(), false);

let direction = Direction::Asc;
assert_eq!(direction.is_asc(), true);

fn is_desc(&self) -> bool

Returns true if the direction is Desc.

Example

use json_api::query::Direction;

let direction = Direction::Asc;
assert_eq!(direction.is_desc(), false);

let direction = Direction::Desc;
assert_eq!(direction.is_desc(), true);

fn reverse(&self) -> Self

Returns a cloned inverse of self.

Example

use json_api::query::Direction;

let asc = Direction::Asc;
let desc = Direction::Desc;

assert_eq!(asc.reverse(), desc);
assert_eq!(desc.reverse(), asc);
