|

|
|
//! 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:

//! | entity | Name of channel passed to `tracing_unbounded` |
|
|
//! | action | One of `send`/`received`/`dropped` |
