I wrote the
errno crate when the
std::io interfaces were still in flux and there was uncertainty around whether they would expose the underlying OS error codes.
But now, a menagerie of
std::io::Error methods exist for just that. It appears that the only thing missing is the ability to modify the errno (
set_errno), which doesn’t see much use in practice.
Are there any applications that use the
errno crate, which cannot use
std::io::Error instead? And if there are none, then should I deprecate this crate?
