Struct OrderClause 

pub struct OrderClause {
    pub target: OrderTarget,
    pub direction: SortDirection,
    pub null_order: NullOrder,
}

Fields

target: OrderTarget

direction: SortDirection

null_order: NullOrder

Implementations

impl OrderClause

pub const fn column(column: &'static str, direction: SortDirection) -> Self

pub const fn relation_scalar( parent_table: &'static str, parent_column: &'static str, related_table: &'static str, related_column: &'static str, value_sql: &'static str, direction: SortDirection, ) -> Self

pub fn nulls_first(self) -> Self

Place NULL values before non-NULL ones for this clause. Use on scheduler / outbox listings where “no scheduled time yet” should sort ahead of every retry-scheduled row.

pub fn nulls_last(self) -> Self

Place NULL values after non-NULL ones (the framework default). Mostly useful when overriding a programmatically-built clause that previously asked for nulls_first.

pub fn is_relation_scalar(&self) -> bool

pub fn targets_column(&self, column: &str) -> bool

pub fn direction(&self) -> SortDirection

Trait Implementations

impl Clone for OrderClause

fn clone(&self) -> OrderClause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OrderClause

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

Formats the value using the given formatter.

impl PartialEq for OrderClause

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