hover_range missing handler?

[pschyska]

In https://github.com/simrat39/rust-tools.nvim/blob/master/lua/rust-tools/hover_range.lua#L26: When request() is called, no handler is passed.

When calling rust_hover_range() I'm getting

Error executing vim.schedule lua callback: ...k/p/start/rust-tools.nvim/lua/rust-tools/utils/utils.lua:106: attempt to call upvalue 'fn' (a nil value)
stack traceback:
        ...k/p/start/rust-tools.nvim/lua/rust-tools/utils/utils.lua:106: in function 'handler'
        ...eovim-unwrapped-0.7.2/share/nvim/runtime/lua/vim/lsp.lua:1025: in function ''
        vim/_editor.lua: in function <vim/_editor.lua:0>

Additionally, using the vim command '<,'>RustHoverRange it says "no range allowed", which is counter-intuitive.

Thanks
