Crate sc_utils

Utilities Primitives for Substrate

This crate provides mpsc::tracing_unbounded function that returns wrapper types to async_channel::Sender<T> and async_channel::Receiver<T>, which register every send/received/dropped action happened on the channel.

Also this wrapper 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
