pub struct Product {
    pub id: ProductId,
    pub name: String,
    pub price: f64,
    pub quantity: u32,
}

Fields

Implementations

impl Product

pub fn new( id: ProductId, name: impl Into<String>, price: f64, quantity: u32, ) -> Self

Creates a new Product instance.

Arguments

• name - Product name
• price - Product price
• quantity - Available stock quantity

Trait Implementations

impl ActorClient<Product> for ProductClient

type Error = ProductError

The resource-specific error type.

fn inner(&self) -> &ResourceClient<Product>

Access the inner generic ResourceClient.

fn map_error(e: FrameworkError) -> Self::Error

Map framework errors to the specific resource error type.

fn get<'life0, 'async_trait>( &'life0 self, id: <T as ActorEntity>::Id, ) -> Pin<Box<dyn Future<Output = Result<Option<T>, Self::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Fetch an entity by ID.

fn delete<'life0, 'async_trait>( &'life0 self, id: <T as ActorEntity>::Id, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Delete an entity by ID.

impl ActorEntity for Product

fn from_create_params( id: ProductId, params: ProductCreate, ) -> Result<Self, Self::Error>

Creates a new Product from creation parameters.

fn on_update<'life0, 'life1, 'async_trait>( &'life0 mut self, update: ProductUpdate, _ctx: &'life1 Self::Context, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Handles updates to the Product entity.

Fields Updated

• price: Product price
• quantity: Available stock quantity

fn handle_action<'life0, 'life1, 'async_trait>( &'life0 mut self, action: ProductAction, _ctx: &'life1 Self::Context, ) -> Pin<Box<dyn Future<Output = Result<ProductActionResult, Self::Error>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Handles custom actions for the Product entity.

Actions

• CheckStock: Returns true if requested quantity is available
• ReserveStock: Decrements stock if available, returns true on success

type Id = ProductId

The unique identifier for this entity (e.g., String, Uuid, u64). Must be convertible from u32 for automatic ID generation.

type Create = ProductCreate

The data required to create a new instance (DTO - Data Transfer Object).

type Update = ProductUpdate

The data required to update an existing instance.

type Action = ProductAction

Enum representing resource-specific operations (e.g., ReserveStock).

type ActionResult = ProductActionResult

The result type returned by custom actions.

type Context = ()

The runtime context (dependencies) injected into the actor. Use () if no dependencies are needed.

type Error = ProductError

The error type for this entity. Must implement std::error::Error for proper error propagation.

fn on_create<'life0, 'life1, 'async_trait>( &'life0 mut self, _ctx: &'life1 Self::Context, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Called immediately after the entity is created and initialized. Use this hook to perform validation or side effects (e.g., checking other actors).

fn on_delete<'life0, 'life1, 'async_trait>( &'life0 self, _ctx: &'life1 Self::Context, ) -> Pin<Box<dyn Future<Output = Result<(), Self::Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Called immediately before the entity is removed from the system.

impl Clone for Product

fn clone(&self) -> Product

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Product

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

Formats the value using the given formatter.
