Debugging Rust with vim and neovim (in Linux)

Step 1

Run :packadd termdebug inside vim/nvim.

This has to be done for every instance, so if you want this to always be enabled then add this to your vimrc.

Also to use rust-gdb rather than standard gdb set let g:termdebugger="rust-gdb".

Step 2

Build your project (so you have something to debug in ./target/debug/<your project>)

Step 3

From within vim/nvim run :Termdebug target/debug/<your project>. This will start gdb.

Now you can set a breakpoint with :Break and finally run the code with :Run.

Commands

For more information see :help Termdebug inside vim/nvim.

Note To see the value of the variable under the cursor: K (shift + k) by default.
