Neovim / rust-analyzer: get a list of all structs / enums to jump to?

Using neovim / rust-analyzer, is it possible to get the following:

  1. we have a cargo workspace

  2. we hit some hot key

  3. we get a list of all structs / enums / traits, and selection = jump to the file / line where it is defined

Maybe irrelevant to your question:

vim.api.nvim_buf_set_keymap(bufnr, 'n', 'gd', '<cmd>lua vim.lsp.buf.definition()<CR>', opts)
vim.api.nvim_buf_set_keymap(bufnr, 'n', '<space>D', '<cmd>lua vim.lsp.buf.type_definition()<CR>', opts)
  • To get all type definitions in your local project at one time, you can use the search command tool like:
rg "struct .* \{"
rg "enum .* \{"

Yes, I have this working in neovim. This works like IntelliJ's 'goto definition" -- it jumps to the struct/enum/fn under the cursor.

IntelliJ has another feature 'goto class' where it opens something that has a text field and a list of all structs/enums; then, as we type characters in the text field, it narrows it down to the structs / enums that matches. We can even type regex!

This is the feature I am trying to replicate, when I remember parts (but not all of) the struct / enum name.

Sounds nice.
Would GitHub - nvim-telescope/telescope.nvim: Find, Filter, Preview, Pick. All lua, all the time. help?

:lua require'telescope.builtin'.lsp_workspace_symbols{}



I was not aware neo-vim was capable of this.

This is more related to my other question: Rust-analyzer as persistent program? than the current one, but since you operate on another level with neovim:

Do you:

(1) never :q in neovim or
(2) somehow avoid paying the cost of 'rust-analyzer boot time' ?

My current finger memory with vim is:

move around in bash
move around in bash

and basically this incurs a rust-analyzer startup time on every nvim session until things like goto-def start working

Well, I never thought about that, but it would be great if nvim can attach to RA again without closing RA's process.
