pub trait HandlerState:
    'static
    + Sync
    + Send
    + Sized {
    type StoreData: Send;
    type WorkerExpiration: WorkerExpiration;
    type WorkerState: WorkerState<StoreData = Self::StoreData>;

    // Required method

    ) -> impl Future<Output = Result<Instance<Self::StoreData, Self::WorkerExpiration, Self::WorkerState>>> + Send;
}

Available on crate feature component-model-async only.

Represents the application-specific state of a web server.

Required Associated Types

type StoreData: Send

The type of the associated data for Stores created using Self::instantiate.

type WorkerExpiration: WorkerExpiration

The type of the WorkerExpiration implementation to be returned from Self::instantiate.

type WorkerState: WorkerState<StoreData = Self::StoreData>

The type of the WorkerState implementation to be returned from Self::instantiate.

Required Methods

fn instantiate( &self, ) -> impl Future<Output = Result<Instance<Self::StoreData, Self::WorkerExpiration, Self::WorkerState>>> + Send

Create a new store and instance for handling one or more requests.

Note that the implementer is responsible for applying a timeout to the guest instantiation if appropriate (e.g. as part of an overall request timeout).

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
