Struct Udev

pub struct Udev { /* private fields */ }

Rust wrapper for the udev struct which represents an opaque libudev context

Most other libudev calls take a struct udev* argument, although whether or not this argument is actually used depends on the version of libudev. In more recent versions the context is ignored, therefore it sometimes works to pass a NULL or a invalid pointer for udev. However older versions, specifically 215 which shipped with Debian 8, expect this to be a valid udev struct. Thus it is not optional.

udev is a ref-counted struct, with references added and removed with udev_ref and udef_unref respectively. This Rust wrapper takes advantage of that ref counting to implement Clone and Drop, so callers need not worry about any C-specific resource management.
