# `Snodo.Subscription.Event`
[🔗](https://github.com/joshrotenberg/snodo/blob/v0.2.0/lib/snodo/subscription/event.ex#L1)

A protocol-neutral event emitted by an application subscription source.

Constructors cover the core `subscriptions/listen` notification families
and a generic extension-owned event envelope. The selected protocol dialect
or negotiated extension adds wire method names and subscription metadata
later, at the transport boundary.

# `kind`

```elixir
@type kind() ::
  :tools_list_changed
  | :prompts_list_changed
  | :resources_list_changed
  | :resource_updated
  | :extension
```

# `t`

```elixir
@type t() :: %Snodo.Subscription.Event{
  extension_id: String.t() | nil,
  kind: kind(),
  metadata: map(),
  params: map(),
  payload: term(),
  selector: map(),
  uri: String.t() | nil
}
```

# `extension`

```elixir
@spec extension(String.t(), map(), term(), keyword()) :: t()
```

Builds an event owned and wire-shaped by a negotiated extension.

# `prompts_list_changed`

```elixir
@spec prompts_list_changed(keyword()) :: t()
```

Builds a `notifications/prompts/list_changed` event.

# `resource_updated`

```elixir
@spec resource_updated(String.t(), keyword()) :: t()
```

Builds a `notifications/resources/updated` event for one absolute URI.

# `resources_list_changed`

```elixir
@spec resources_list_changed(keyword()) :: t()
```

Builds a `notifications/resources/list_changed` event.

# `tools_list_changed`

```elixir
@spec tools_list_changed(keyword()) :: t()
```

Builds a `notifications/tools/list_changed` event.
