Subscriptions close once a client is dropped #1591
Description
jsonrpsee_core::client::Subscription closes once the client used to subscribe is dropped. This is surprising, and not documented clearly.
IMO Subscription should have a lifetime parameter from the client, and generated client subscription methods should look something like
#[async_trait]
pub trait RpcClient: SubscriptionClient {
...
// Subscription method returns `Subscription` object in case of success.
async fn sub<'a>(&'a self) -> Result<Subscription<'a, Self, String>, Error> {
// ...
}
}
