Implementations

impl IsUnsubscribed

pub fn is_unsubscribed(&self) -> bool

Returns true if the unsubscribe method has been invoked or the subscription has been canceled.

This can be called multiple times as the element in the channel is never removed.

pub async fn unsubscribed(&self)

Wrapper over tokio::sync::mpsc::Sender::closed

Cancel safety

This method is cancel safe. Once the channel is closed, it stays closed forever and all future calls to closed will return immediately.
