Struct SubscriptionsListenParams 

pub struct SubscriptionsListenParams {
    pub notifications: Option<SubscriptionFilter>,
    pub meta: Option<Value>,
}

Parameters for the subscriptions/listen RPC (SEP-2575 / SEP-2567).

subscriptions/listen is sent by the client over HTTP POST to open a server-to-client notification stream (SSE). The server responds with Content-Type: text/event-stream and streams zero or more notifications/* events until the client disconnects.

Under SEP-2567 (sessionless), the stream lifetime is scoped to the single request. Only servers whose negotiated protocol version is >= 2026-07-28 enable this path; older servers return a Method Not Found (-32601) error.

The struct takes no parameters today; the empty struct is reserved so future SEPs can add optional fields without breaking callers.

Fields

notifications: Option<SubscriptionFilter>

SEP-2575: the notification types the client opts in to on this stream. The draft schema requires this field; it is optional here so existing callers keep compiling, and the transport enforces presence on the 2026-07-28 path (#952).

meta: Option<Value>

Optional protocol-level metadata.
