Description

This adds a method to the callback, similar to Rust's filter_map, which allows to reform a callback, but also suppress the emit in case the reform function returns None.

One suggestion to the documentation, feel free to suggest an even better one.

The test cases seem fine, and the method has a clear purpose to me.

One thing I almost forgot: Would it make sense to have this return Callback<T, Option<OUT>> instead - and generalize for any Callback<IN, OUT>?

EDIT: If returning Option<OUT> is not desirable, perhaps requiring OUT: Default and keeping the same OUT as its output makes most sense.

Hm, that sounds like an interesting idea. I will try to amend the PR with this.

Looks good. Thanks for also improving callback test coverage

Seems like failed test are related to tokio-rs/tokio#4973. Can you update the Cargo.toml to pin tokio to a working version? That should make a CI green

CI should now be fixed by #2866 and #2867. Could you please rebase from / merge the latest master branch?

Allow skipping a callback when reforming

This adds a method to the callback, similar to Rust's filter_map, which
allows to reform a callback, but also suppress the emit in case
the reform function returns `None`.

Implement filter_reform for all Callback output types
291beaf 
As suggested in the PR, this implements filter_reform for all output
types of callbacks by mapping to `Option<OUT>`.
@ctron
Fix clippy error
041e4bb 
Although I believe that the code is more readable/understandable with
an explicit map, I am not sure adding a clippy exception just for that
is justified. So I applied the clippy suggestion.
