Struct iota_metrics::metered_channel::WeakSender
source · pub struct WeakSender<T> { /* private fields */ }
Expand description
An [mpsc::WeakSender
] with an [IntGauge
]
counting the number of currently queued items.
Implementations§

impl<T> WeakSender<T>
sourcepub fn upgrade(&self) -> Option<Sender<T>>
pub fn upgrade(&self) -> Option<Sender<T>>
Upgrades the WeakSender
to a strong Sender
, if the underlying
channel still exists. This allows the WeakSender
to regain full
control over the channel, enabling it to send messages again. If the
underlying channel has been dropped, None
is returned. Otherwise, it
returns a Sender
with the upgraded reference and the associated
gauge for resource tracking.
