Struct HandleRef 

pub struct HandleRef<'a> { /* private fields */ }

A borrowed reference to a Handle.

Mostly useful as part of a WaitItem.

Implementations

impl<'a> HandleRef<'a>

pub fn raw_handle(&self) -> zx_handle_t

pub fn duplicate(&self, rights: Rights) -> Result<Handle, Status>

pub fn signal( &self, clear_mask: Signals, set_mask: Signals, ) -> Result<(), Status>

pub fn wait(&self, signals: Signals, deadline: Time) -> Result<Signals, Status>

pub fn wait_async( &self, port: &Port, key: u64, signals: Signals, options: WaitAsyncOpts, ) -> Result<(), Status>

Trait Implementations

impl<'a> AsHandleRef for HandleRef<'a>

fn as_handle_ref(&self) -> HandleRef<'_>

Get a reference to the handle. One important use of such a reference is for object_wait_many.

fn raw_handle(&self) -> zx_handle_t

Interpret the reference as a raw handle (an integer type). Two distinct handles will have different raw values (so it can perhaps be used as a key in a data structure).

fn signal_handle( &self, clear_mask: Signals, set_mask: Signals, ) -> Result<(), Status>

Set and clear userspace-accessible signal bits on an object. Wraps the zx_object_signal syscall.

fn wait_handle( &self, signals: Signals, deadline: Time, ) -> Result<Signals, Status>

Waits on a handle. Wraps the zx_object_wait_one syscall.

fn wait_async_handle( &self, port: &Port, key: u64, signals: Signals, options: WaitAsyncOpts, ) -> Result<(), Status>

Causes packet delivery on the given port when the object changes state and matches signals. zx_object_wait_async syscall.

impl<'a> Clone for HandleRef<'a>

fn clone(&self) -> HandleRef<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for HandleRef<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for HandleRef<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for HandleRef<'a>

fn eq(&self, other: &HandleRef<'a>) -> 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.
