Removing directories

Finally, let's see the code to remove directories:

#[async]
fn handle_cmd(mut self, cmd: Command) -> Result<Self> {
    match cmd {
        Command::Rmd(path) => self = await!(self.rmd(path))?,
        // …
    }
}

Like for the previous commands, we add a new case that calls the method that will handle it:

use std::fs::remove_dir_all;

#[async]
fn rmd(mut self, directory: PathBuf) -> Result<Self> {
    let path = self.cwd.join(&directory);
    let (new_self, res) = self.complete_path(path);
    self = new_self;
    if let Ok(dir) = res {
        if remove_dir_all(dir).is_ok() {
            self = await!(self.send(Answer::new(ResultCode::RequestedFileActionOkay,
                                                "Folder successfully removed")))?;
            return Ok(self);
        }
    }
    self = await!(self.send(Answer::new(ResultCode::FileNotFound,
                                        "Couldn't remove folder")))?;
    Ok(self)
}
