[prestwich]

there should be some trait bound on new to prevent users from creating IpcConnect instances that don't work. The From bound is good but not quite sufficient

[prestwich]

impl<T> IpcConnect<T> {
    pub fn new(inner: T) -> Self
    where
        Self: alloy_pubsub::PubSubConnect,
    {
        Self { inner }
    }
}
