How to eplore defined elements in a Rust program via Rustic?

[parvizfarnia]

Hi,

With IDE's such as Netbeans, Eclipse, VSCode, etc. one has the possibility of having an explorer as a sidebar which includes the entire project folder with all source files but also everything else: all defined variables, classes, methods, functions, etc.

I use Emacs Dired for navigating between files in my project which works fine but for the rest, that is, accessing rapidly different element defined in my Rust programs: Structs, their members, Enums, functions, Traits, etc. so far, I haven't found a user-friendly navigation tool (sidebar).

I checked Rustic's documentation, the closest thing that I found was using xref (M-.) by selecting a given word in the code. But even that, doesn't seem to work always correctly and does not necessarily take me to the exact location where the specific element is defined in my code.

So here is my question: Is it me who doesn't know how to use rustic efficiently or it's simply the fact that such functionnalities in terms of code navigation as I explained above are simply missing in rustic (at least in its current version)?

Thansk in advance

Probably you are looking for lsp-treemacs: https://github.com/emacs-lsp/lsp-treemacs#lsp-treemacs-symbols ?

Seems interesting. There are elements which are present but many (structures and enums) are absent. So if I understand correctly rustic itself doesn't provide this navigation functionality that I explained above, right?

Yeah, you're right.

But even that, doesn't seem to work always correctly and does not necessarily take me to the exact location where the specific element is defined in my code.

I use rustic along with lsp-mode (and rust-analyzer) and the lsp's provided functionality for goto definition, finding references and finding type definitions have worked at exact locations for me.
