Expand description

A trait to get a reference to the underlying handle of an object.

Required Methods§

source

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

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

Provided Methods§

source

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).

source

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.

source

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

Waits on a handle. Wraps the zx_object_wait_one syscall.

source

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.

source

fn get_name(&self) -> Result<Name, Status>

Get the Property::NAME property for this object.

Wraps a call to the zx_object_get_property syscall for the ZX_PROP_NAME property.

source

fn set_name(&self, name: &Name) -> Result<(), Status>

Set the Property::NAME property for this object.

The name’s length must be less than sys::ZX_MAX_NAME_LEN, i.e. name.to_bytes_with_nul().len() <= sys::ZX_MAX_NAME_LEN, or Err(Status::INVALID_ARGS) will be returned.

Wraps a call to the zx_object_get_property syscall for the ZX_PROP_NAME property.

source

fn basic_info(&self) -> Result<HandleBasicInfo, Status>

Wraps the zx_object_get_info syscall for the ZX_INFO_HANDLE_BASIC topic.

source

fn count_info(&self) -> Result<HandleCountInfo, Status>

Wraps the zx_object_get_info syscall for the ZX_INFO_HANDLE_COUNT topic.

source

fn get_koid(&self) -> Result<Koid, Status>

Returns the koid (kernel object ID) for this handle.
