Hide a specific trait in autocomplete

[oriongonza]

I love color-eyre but the OwoColorize trait adds a lot of noise to autocomplete.

Could we get a way to hide some specific traits?
I'd personally also use it for Any

Might be nice if it could not only hide specific traits but also methods from specific (sub)modules/crates.

In the example above that could be hiding all the owo_colors items but keeping the color_eyre items.
