//! 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` |
