Agree! This is a useful for some people in china.

Using ENV doesn't seem to work. For example, `http_proxy=http://127.0.0.1:7777 ntfy -b telegram send "ntfy test"` would produce ``` WARNING: Retrying (Retry(total=2, connect=None, read=None, redirect=None)) after connection broken by 'NewConnectionError(': Failed...

I got it. `https_proxy=http://127.0.0.1:7777` works. Within python we can use `os.environ["https_proxy"] = "http://127.0.0.1:7777"` ref https://pypi.org/project/telegram-send/#how-to-use-a-proxy

Are we able to configure environment variable or proxy in ntfy.yml? If so, it would be convenient to assign the ENV without polluting the whole environment. For example, I want...

Seems a lot of libraries under [googleapis](https://github.com/googleapis) uses Protobuf, so they don't need to handle base64 problem.

I am not quite familiar with the design of this repo. Is there any specific design consideration that discourage us from using grpc interface or using async interface of reqwest?

Current implementation for linux and windows can be found at [repo](https://github.com/xiaoniu-578fa6bff964d005/core_affinity_rs). I don't have any idea on how to implement on Mac, nor do I have a device for testing....

Current implementation of windows use [GetCurrentProcessorNumber ](https://docs.microsoft.com/en-us/windows/win32/api/processthreadsapi/nf-processthreadsapi-getcurrentprocessornumber) API. Seems it is not applicable for more than 64 logical processors.

Currently I wish to apply a `FnMut(&mut T)` on all the data stored in a tree. I wish to implement it by traverse with NodeMut instead of recursion.

In that case, what traverse order would be used for `map_in_place`? Some times the order matters.
