Struct Ordered 

pub struct Ordered {
    pub this: Expression,
    pub desc: bool,
    pub nulls_first: Option<bool>,
    pub explicit_asc: bool,
    pub with_fill: Option<Box<WithFill>>,
}

Represent an expression with sort direction and null ordering.

Used inside ORDER BY clauses, window frame ORDER BY, and index definitions. When desc is false the sort is ascending. The nulls_first field controls the NULLS FIRST / NULLS LAST modifier; None means unspecified (database default).

Fields

this: Expression

The expression to sort by.

desc: bool

Whether the sort direction is descending (true) or ascending (false).

nulls_first: Option<bool>

Some(true) = NULLS FIRST, Some(false) = NULLS LAST, None = unspecified.

explicit_asc: bool

Whether ASC was explicitly written (not just implied)

with_fill: Option<Box<WithFill>>

ClickHouse WITH FILL clause

Implementations

impl Ordered

pub fn asc(expr: Expression) -> Self

pub fn desc(expr: Expression) -> Self

Trait Implementations

impl Clone for Ordered

fn clone(&self) -> Ordered

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Ordered

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Ordered

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Ordered

fn eq(&self, other: &Ordered) -> 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 Ordered

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
