Function open 

pub fn open<T: AsRef<Path>>(
    path: T,
    line: Option<usize>,
    col: Option<usize>,
) -> Result<()>

Opens a file in the editor and positions the cursor at the specified line and column.

Errors

• If execution of “edit” command via crate::common::exec_vim_cmd fails.
• If setting the cursor position via Window::set_cursor fails.

Rationale

Executes two Neovim commands, one to open the file and one to set the cursor because it doesn’t seems possible to execute a command line “edit +call\n cursor(LNUM, COL)”.
