Rust GDB frontend?

Hi Guys! What's the story about Rust debugger (particularly GDB) frontends?

I'm particularly looking for integration with Vim(Neovim) / Atom, however I might consider other solutions as well. What do you use / recommend?

I have slightly adapted Neovim gdb proof-of-concept, to be found at Rust GDB NVim frontend · GitHub (see commands and keybindings at the very bottom of the file).

It seems to be bearable to work with. Nevertheless I wonder, if you could point me to other alternatives and solutions (other than Rust RDT)? Hope it makes any sense..
