Crate xdg_utils

Query system for default apps using XDG MIME databases.

The xdg-utils library provides dependency-free (except for std) Rust implementations of some common functions in the freedesktop project xdg-utils.

What is implemented?

• Function query_default_app performs like the xdg-utils function binary_to_desktop_file
• Function query_mime_info launches the mimetype or else the file command.

Some of the utils may be implemented by combining these functions with other functions in the Rust standard library.
