How to Get the Fully Qualified Name of a Symbol Under the Cursor in Rust Using coc.nvim

[loyalpartner]

I want to get the full path (fully qualified name) of the symbol under the mouse cursor, such as in Rust code where build_session is represented as rustc_session::session::build_session. Does coc.nvim have an API that can achieve this?

You can set "rust-analyzer.trace.server": "verbose" to check whether rust-analyzer returns full path of the symbol, I don't think so as LSP only returns documentSymbol name.
