# Push.Class

Constructable static type produced by `Push.Service`.

## Signatures

```ts
interface Class<Self, Id extends string, A, E, B, E2> extends Service<Self, Id, A, E, B, E2> {
    new (): Service<Self, Id, A, E, B, E2>;
}
```

## Why

The construct signature supports the class-extension pattern used by Effect
services while retaining the complete static Push API.

## Ownership and lifetime

Constructing the class returns its static service value; it does not acquire,
subscribe to, or dispose the installed Push.

## Construct signatures

Returns the static service value when used through the class pattern.

## Construct signatures: Why

The construct signature allows `class X extends Push.Service(...)` while
preserving the service's precise static type.

## Construct signatures: Ownership and lifetime

Construction acquires nothing; the resulting value still resolves its
concrete Push from the current Effect Context.

## Examples

```ts
import * as Push from "@typed/fx/Push"

class Events extends Push.Service<Events, string, never, string>()("Events") {}
const ServiceClass: Push.Push.Class<Events, "Events", string, never, string, never> = Events
```

```ts
import * as Push from "@typed/fx/Push"
class Events extends Push.Service<Events, string, never, string>()("Events") {}
const events = new Events()
```
