Struct udev::MonitorBuilder

pub struct MonitorBuilder { /* 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 MonitorBuilder

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

Creates a new Monitor.

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

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

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.

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

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

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

Removes all filters currently set on the monitor.

fn listen(self) -> Result<MonitorSocket>

Listens for events matching the current filters.

This method consumes the Monitor.
