Enum SortOrder 

pub enum SortOrder {
    Ascending,
    Descending,
}

Specifies whether sorting (in an index or in an ORDER BY clause) happens in ascending or descending order.

Variants

Ascending

Sort values in increasing numeric or lexicographical order.

Descending

Sort values in decreasing numeric or lexicographical order.

impl Ord for SortOrder

fn cmp(&self, other: &SortOrder) -> 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 SortOrder

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for SortOrder

fn partial_cmp(&self, other: &SortOrder) -> 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.
