Enum OrderBy 

#[repr(i32)]
pub enum OrderBy {
    Unspecified = 0,
    Asc = 1,
    Desc = 2,
}

OrderBy defines the sorting order

Variants

Unspecified = 0

ORDER_BY_UNSPECIFIED specifies an unknown sorting order. OrderBy defaults to ASC in this case.

Asc = 1

ORDER_BY_ASC defines ascending order

Desc = 2

ORDER_BY_DESC defines descending order

Implementations

impl OrderBy

pub fn is_valid(value: i32) -> bool

Returns true if value is a variant of OrderBy.

pub fn from_i32(value: i32) -> Option<OrderBy>

Converts an i32 to a OrderBy, or None if value is not a valid variant.

Trait Implementations

impl Clone for OrderBy

fn clone(&self) -> OrderBy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderBy

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

Formats the value using the given formatter.

impl Default for OrderBy

fn default() -> OrderBy

Returns the “default value” for a type.

impl Hash for OrderBy

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for OrderBy

fn cmp(&self, other: &OrderBy) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for OrderBy

fn eq(&self, other: &OrderBy) -> 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 PartialOrd for OrderBy

fn partial_cmp(&self, other: &OrderBy) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
