Enum AggregationStrategy 

pub enum AggregationStrategy {
    First,
    Union,
    Intersect,
    Concat,
    Largest,
    Fastest,
}

Strategy for aggregating results from multiple sources

Variants

First

Use first successful result

Union

Merge all results (union)

Intersect

Intersect results (only common bindings)

Concat

Concatenate results preserving source info

Largest

Use result with most bindings

Fastest

Use result with fastest response

Trait Implementations

impl Clone for AggregationStrategy

fn clone(&self) -> AggregationStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AggregationStrategy

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

Formats the value using the given formatter.

impl Default for AggregationStrategy

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AggregationStrategy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AggregationStrategy

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for AggregationStrategy

impl Eq for AggregationStrategy
