DAP support rust

Create a .solution file in your working directory. Then pass the -g parameter to the compiler like this

[HELLO WORLD]
entry_point="/path/to/my/entry_point_file/main.rs"
output="/path/where/the/program/will/be/written/hello_world"
parameters="-g"

That will tell the compiler to compile in debug mode.

How to setup DAP to debug with C#

Please note that this section has nothing to do with compiler.nvim. I'm documenting this to make your life easier. To debug C# with DAP you have to:

• Install the package lldb in your system
• Setup DAP for rust

Here you have an example of how to configure DAP for rust

local dap = require("dap")

-- Rust
dap.adapters.lldb = {
  type = 'executable',
  command = '/usr/bin/lldb-vscode', -- path of your netcoredbg executable
  name = 'lldb'
}
dap.configurations.rust = {
  {
    name = 'Launch',
    type = 'lldb',
    request = 'launch',
    program = function() -- Ask the user what executable wants to debug
      return vim.fn.input('Path to executable: ', vim.fn.getcwd() .. '/bin/program', 'file')
    end,
    cwd = '${workspaceFolder}',
    stopOnEntry = false,
    args = {},
    initCommands = function() -- add rust types support
      -- Find out where to look for the pretty printer Python module
      local rustc_sysroot = vim.fn.trim(vim.fn.system('rustc --print sysroot'))

      local script_import = 'command script import "' .. rustc_sysroot .. '/lib/rustlib/etc/lldb_lookup.py"'
      local commands_file = rustc_sysroot .. '/lib/rustlib/etc/lldb_commands'

      local commands = {}
      local file = io.open(commands_file, 'r')
      if file then
        for line in file:lines() do
    table.insert(commands, line)
        end
        file:close()
      end
      table.insert(commands, 1, script_import)

      return commands
    end,
  }
}

How to check if everything works

Compile your program with Build solution, add a break point to your code, and then run DAP. You will see something like this.

Congratulations, now you can compile and debug Rust.

Troubleshooting

• If you find any issue while configuring DAP, run :DapSetLogLevel trace and :DapShowLog to find the reason.
