Struct Aggregation

pub struct Aggregation {
    pub function: KoronFunction,
    pub column: String,
    pub alias: Option<String>,
}

An aggregation that’s computed over the values of a column.

Represents an occurrence of an aggregation such as function(column) within the SELECT clause of a query.

Fields

function: KoronFunction

The function used as aggregator of column’s values.

column: String

The name of the column on which the function is executed.

alias: Option<String>

The alias that’s assigned to the result of the function: function(column) AS alias.

Trait Implementations

impl Clone for Aggregation

fn clone(&self) -> Aggregation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ComposeSchema for Aggregation

fn compose(generics: Vec<RefOr<Schema>>) -> RefOr<Schema>

impl Debug for Aggregation

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

Formats the value using the given formatter.

impl Default for Aggregation

fn default() -> Aggregation

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Aggregation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl IntoParams for Aggregation

fn into_params( parameter_in_provider: impl Fn() -> Option<ParameterIn>, ) -> Vec<Parameter>

Provide Vec of openapi::path::Parameters to caller. The result is used in utoipa-gen library to provide OpenAPI parameter information for the endpoint using the parameters.

impl PartialEq for Aggregation

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl ToSchema for Aggregation

fn name() -> Cow<'static, str>

Return name of the schema.

fn schemas(schemas: &mut Vec<(String, RefOr<Schema>)>)

Implement reference utoipa::openapi::schema::Schemas for this type.

impl Eq for Aggregation

impl StructuralPartialEq for Aggregation
