Struct UdevQueue 

pub struct UdevQueue { /* private fields */ }

Represents the current event queue in the udev daemon.

Implementations

impl UdevQueue

pub fn new(udev: Arc<Udev>) -> Self

Creates a new UdevQueue.

pub fn create<Q: Into<UdevEntryList>>( udev: Arc<Udev>, queue_list: Q, fd: i32, ) -> Self

Creates a new UdevQueue from the provided parameters.

pub const fn udev(&self) -> &Arc<Udev>

Gets a reference to the Udev context.

pub const fn queue_list(&self) -> &UdevList

Gets a reference to the queue list UdevList.

pub fn queue_list_mut(&mut self) -> &mut UdevList

Gets a mutable reference to the queue list UdevList.

pub fn set_queue_list<Q: Into<UdevEntryList>>(&mut self, queue_list: Q)

Sets the queue list UdevEntryList.

pub fn with_queue_list<Q: Into<UdevEntryList>>(self, queue_list: Q) -> Self

Builder function that sets the queue list UdevEntryList.

pub fn len(&self) -> usize

Gets the length of the UdevQueue.

pub fn is_empty(&self) -> bool

Gets whether the UdevQueue is empty.

pub const fn fd(&self) -> i32

Gets the UdevQueue file descriptor.

pub fn set_fd(&mut self, val: i32)

Sets the UdevQueue file descriptor.

pub fn with_fd(self, val: i32) -> Self

Builder function that sets the UdevQueue file descriptor.

pub fn get_fd(&mut self) -> Result<i32>

Gets a file descriptor to watch for a queue to become empty.

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

Clears the watched file descriptor for queue changes.

Safety

Users must ensure that every UdevQueue has a unique file descriptor, if the descriptor is non-negative.

Returns: Ok(()) on success, Err(Error) otherwise.

pub fn udev_is_active(&self) -> bool

Checks if Udev is active on the system.

pub fn queue_is_empty(&self) -> bool

Gets whether UdevQueue is currently processing any events.

Trait Implementations

impl Clone for UdevQueue

fn clone(&self) -> UdevQueue

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for UdevQueue

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for UdevQueue

fn default() -> UdevQueue

Returns the “default value” for a type.

impl PartialEq for UdevQueue

fn eq(&self, other: &UdevQueue) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
