Variants

PermissionDenied

A standard permission denied error.

This will be a common error, since some files in the procfs filesystem are only readable by the root user.

NotFound

This might mean that the process no longer exists, or that your kernel doesn’t support the feature you are trying to use.

Io(Error)

Any other IO error (rare).

Other(String)

Any other non-IO error (very rare).
