Base trait for all entities in the system.

This trait provides the fundamental metadata needed for any entity type. All entities have:

• id: Unique identifier
• type: Entity type name (e.g., “user”, “product”)
• created_at: Creation timestamp
• updated_at: Last modification timestamp
• deleted_at: Soft deletion timestamp (optional)
• status: Current status of the entity

Required Associated Types

type Service: Send + Sync

The service type that handles operations for this entity

Required Methods

fn resource_name() -> &'static str

The plural resource name used in URLs (e.g., “users”, “companies”)

fn resource_name_singular() -> &'static str

The singular resource name (e.g., “user”, “company”)

fn service_from_host( host: &Arc<dyn Any + Send + Sync>, ) -> Result<Arc<Self::Service>>

Extract the service instance from the application host/state

fn id(&self) -> Uuid

Get the unique identifier for this entity instance

fn entity_type(&self) -> &str

Get the entity type name

fn created_at(&self) -> DateTime<Utc>

Get the creation timestamp

fn updated_at(&self) -> DateTime<Utc>

Get the last update timestamp

fn deleted_at(&self) -> Option<DateTime<Utc>>

Get the deletion timestamp (soft delete)

fn status(&self) -> &str

Get the entity status

Provided Methods

fn is_deleted(&self) -> bool

Check if the entity has been soft-deleted

fn is_active(&self) -> bool

Check if the entity is active (status == “active” and not deleted)

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
