Struct Job 

pub struct Job(/* private fields */);

An object representing a Zircon job.

As essentially a subtype of NullableHandle, it can be freely interconverted.

Implementations

impl Job

Wraps the zx_object_signal syscall.

Wraps the zx_object_wait_one syscall.

Trait Implementations

impl AsHandleRef for Job

fn as_handle_ref(&self) -> Unowned<'_, NullableHandle>

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

fn raw_handle(&self) -> u32

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 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.

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

Get the Property::NAME property for this object.

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

Set the Property::NAME property for this object.

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

Wraps the zx_object_get_info syscall for the ZX_INFO_HANDLE_BASIC topic.

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

Wraps the zx_object_get_info syscall for the ZX_INFO_HANDLE_COUNT topic.

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

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

impl CompatFrom<Job> for Job

Available on crate feature fuchsia only.

fn compat_from(value: Job) -> Job

Converts value into a value of this type.

impl Debug for Job

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

Formats the value using the given formatter.

where E: HandleEncoder + ?Sized,

fn encode( self, encoder: &mut E, out: &mut MaybeUninit<WireJob>, constraint: <WireJob as Constrained>::Constraint, ) -> Result<(), EncodeError>

Encodes this value into an encoder and output.

const COPY_OPTIMIZATION: CopyOptimization<Self, W> = _

Whether the conversion from Self to W is equivalent to copying the raw bytes of Self.

impl<E> EncodeOption<WireOptionalJob, E> for Job

where E: HandleEncoder + ?Sized,

fn encode_option( this: Option<Job>, encoder: &mut E, out: &mut MaybeUninit<WireOptionalJob>, constraint: (), ) -> Result<(), EncodeError>

impl From<Job> for NullableHandle

fn from(x: Job) -> NullableHandle

Converts to this type from the input type.

impl From<NullableHandle> for Job

fn from(handle: NullableHandle) -> Job

Converts to this type from the input type.

impl FromWire<WireJob> for Job

fn from_wire(wire: WireJob) -> Job

Converts the given wire to this type.

Duplicate a handle, possibly reducing the rights available. Wraps the zx_handle_duplicate syscall.

fn replace_handle(self, rights: Rights) -> Result<Self, Status>
