Enum Direction 

pub enum Direction {
    Asc,
    Desc,
}

Sort direction for Query::order_by, read from a query string as asc or desc.

Deserializes from "asc"/"desc" (any case), so a handler can take it straight from ?direction=desc; the column must still come from your code (see Query::order_by).

Examples

use ocre::Direction;

let direction: Direction = serde_json::from_str(r#""desc""#).unwrap();
assert_eq!(direction, Direction::Desc);
assert_eq!(direction.as_sql(), "DESC");
assert_eq!(Direction::default(), Direction::Asc);

Variants

Asc

Smallest first (ASC).

Desc

Largest first (DESC).

Implementations

impl Direction

pub fn as_sql(self) -> &'static str

ASC or DESC.

Examples

assert_eq!(ocre::Direction::Asc.as_sql(), "ASC");

Trait Implementations

impl Clone for Direction

fn clone(&self) -> Direction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Direction

impl Debug for Direction

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

Formats the value using the given formatter.

impl Default for Direction

fn default() -> Direction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Direction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Direction

impl PartialEq for Direction

fn eq(&self, other: &Direction) -> 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.

impl Serialize for Direction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
