Struct SortField

pub struct SortField {
    pub source_id: i32,
    pub transform: Transform,
    pub direction: SortDirection,
    pub null_order: NullOrder,
}

Entry for every column that is to be sorted

Fields

source_id: i32

A source column id from the table’s schema

transform: Transform

A transform that is used to produce values to be sorted on from the source column.

direction: SortDirection

A sort direction, that can only be either asc or desc

null_order: NullOrder

A null order that describes the order of null values when sorted.

Implementations

impl SortField

pub fn builder() -> SortFieldBuilder<((), (), (), ())>

Create a builder for building SortField. On the builder, call .source_id(...), .transform(...), .direction(...), .null_order(...) to set the values of the fields. Finally, call .build() to create the instance of SortField.

Trait Implementations

impl Clone for SortField

fn clone(&self) -> SortField

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SortField

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SortField

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for SortField

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

Formats the value using the given formatter.

impl PartialEq for SortField

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
