Utilities Primitives for Substrate
Features
metered
This feature changes the behaviour of the function mpsc::tracing_unbounded.
With the disabled feature this function is an alias to futures::channel::mpsc::unbounded.
However, when the feature is enabled it creates wrapper types to UnboundedSender<T>
and UnboundedReceiver<T> to register every send/received/dropped action happened on
the channel.
Also this feature creates and registers a prometheus vector with name unbounded_channel_len and labels:
| Label | Description |
|---|---|
| entity | Name of channel passed to tracing_unbounded |
| action | One of send/received/dropped |
