Enum Cardinality 

pub enum Cardinality {
    OneToOne,
    OneToMany,
    ManyToOne,
    ManyToMany,
}

Structural cardinality of a service-to-service relationship.

Standard ER cardinality covering the four relationship types. Each variant maps to a default NavigationHint via Cardinality::default_navigation.

Variants

OneToOne

OneToMany

ManyToOne

ManyToMany

Implementations

impl Cardinality

pub fn default_navigation(&self) -> NavigationHint

Returns the default navigation hint for this cardinality.

• OneToOne -> Inline (embed related data in current view)
• ManyToOne -> Link (navigable link to parent entity)
• OneToMany -> Nested (nested list within current view)
• ManyToMany -> Nested (nested list within current view)

Trait Implementations

impl Clone for Cardinality

fn clone(&self) -> Cardinality

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Cardinality

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Cardinality

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Cardinality

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

The name of the generated JSON Schema.

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

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for Cardinality

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

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 Cardinality

impl Eq for Cardinality
