• I have searched the existing rust-analyzer issues (if applicable).
• I can reproduce the issue with stable Neovim (not a distribution or nightly) and the minimal config.
• This is an issue about rustaceanvim, not rust-analyzer or Neovim.
• This is not an issue with autocompletion.

How to reproduce the issue

config with rustaceanvim, nvim-dap and nvim-dap-ui.
make any rust project.

try to debug in nvim-dap-ui with codelldb and see that rust pretty printers are not properly loaded

this seems to be a new issue with both rustc 1.85 and codelldb v1.11.4. All was fine with rustc 1.81 and codelldb 1.10.

Seems that codelldb v1.11.4 has introduced a new variable to automaticcaly load rust pretty printers.

solved by adding the following line in internal.lua / function load_dap_configuration :
--52,58
  local dap_config = {
    name = 'Rust debug client',
    type = type,
    request = 'launch',
    stopOnEntry = false,
++    sourceLanguages = {'rust'},
  }
--
this was inspired by https://github.com/vadimcn/codelldb/blob/master/MANUAL.md#python-scripting, chapter "Rust Language Support"

Expected behaviour

codelldb shall be able to load rust pretty printers for project's target, so all rust types shall be properly interpreted inside dap-ui variable inspector

Actual behaviour

Instead, only raw types are displayed (for instance alloc::vec::Vec<double, alloc::alloc::Global> instead of double[x]) indicating that codelldb has not loaded rust pretty printers
