Struct EntityState 

pub struct EntityState<S = ()> {
    pub uid: Uuid,
    pub entity_version: u64,
    pub parent_uid: Option<Uuid>,
    pub created_at: OffsetDateTime,
    pub updated_at: OffsetDateTime,
    pub main: Option<EntityStateComponent<S>>,
    pub components: HashMap<String, EntityStateComponent>,
}

State of an entity.

Contains a main state, which will be managed by the owning service that manages the entity.

Additional services may inject their own state, which will be found in Self::components.

Fields

uid: Uuid

Globally unique UUID.

entity_version: u64

Version of the entity. All modifications to metadata or spec will increment this version.

parent_uid: Option<Uuid>

UUID of the parent entity. This is only set if the entity is a child of another entity.

created_at: OffsetDateTime

Creation timestamp.

updated_at: OffsetDateTime

Last update timestamp. Will be set on each metadata or spec change, but not on state changes.

main: Option<EntityStateComponent<S>>

The primary state of the entity, managed by the owning service.

components: HashMap<String, EntityStateComponent>

Additional entity states, managed by services other than the entity owners.

Trait Implementations

impl<S: Clone> Clone for EntityState<S>

fn clone(&self) -> EntityState<S>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<S: Debug> Debug for EntityState<S>

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

Formats the value using the given formatter.

impl<'de, S> Deserialize<'de> for EntityState<S>

where S: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<S: JsonSchema> JsonSchema for EntityState<S>

fn schema_name() -> String

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 is_referenceable() -> bool

Whether JSON Schemas generated for this type should be re-used where possible using the $ref keyword.

impl<S: PartialEq> PartialEq for EntityState<S>

fn eq(&self, other: &EntityState<S>) -> 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<S> Serialize for EntityState<S>

where S: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
