pub struct OrderByExpression {
    pub expression: Expression,
    pub ascending: bool,
    pub nulls_first: Option<bool>,
}

ORDER BY expression

Fields

expression: Expression

ascending: bool

nulls_first: Option<bool>

None = default (NULLS LAST for ASC, NULLS FIRST for DESC in SQL standard) Some(true) = NULLS FIRST Some(false) = NULLS LAST

Trait Implementations

impl Clone for OrderByExpression

fn clone(&self) -> OrderByExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderByExpression

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

Formats the value using the given formatter.

impl Display for OrderByExpression

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

Formats the value using the given formatter.

impl PartialEq for OrderByExpression

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