Function load_dict 

pub fn load_dict<P: AsRef<Path>>(
    path: P,
) -> Result<Box<dyn DictReader>, DictError>

Load a DictReader from file.

This function loads a Dictreader from a file and transparently selects the correct reader using the file type extension, so the callee doesn’t need to care about compression (.dz).

Errors

The function can return a DictError, which can either occur if a I/O error occurs, or when the GZ compressed file is invalid.
