Struct libudev::Monitor

pub struct Monitor<'a> { /* fields omitted */ }

Monitors for device events.

A monitor communicates with the kernel over a socket. Filtering events is performed efficiently in the kernel, and only events that match the filters are received by the socket. Filters must be setup before listening for events.

Methods

impl<'a> Monitor<'a>

pub fn new(context: &'a Context) -> Result<Self>

Creates a new Monitor.

pub fn match_subsystem<T: AsRef<OsStr>>(&mut self, subsystem: T) -> Result<()>

Adds a filter that matches events for devices with the given subsystem.

pub fn match_subsystem_devtype<T: AsRef<OsStr>, U: AsRef<OsStr>>(
    &mut self,
    subsystem: T,
    devtype: U
) -> Result<()>

Adds a filter that matches events for devices with the given subsystem and device type.

pub fn match_tag<T: AsRef<OsStr>>(&mut self, tag: T) -> Result<()>

Adds a filter that matches events for devices with the given tag.

pub fn clear_filters(&mut self) -> Result<()>

Removes all filters currently set on the monitor.

pub fn listen(self) -> Result<MonitorSocket<'a>>

Listens for events matching the current filters.

This method consumes the Monitor.
