I have realized this function, but my editor cannot receive it .. I cannot understand why

Finished. I should state that I have realize onhover in initialize..

Yes, the server must specify what capabilities it supports in the InitializeResult returned by the initialize() method. Another option is to not specify statically and instead register for the capability dynamically using Client::register_capability() (assuming the client indicated it supports dynamic registration in InitializeParams)
