Struct Port 

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

An object representing a Zircon port.

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

Implementations

impl Port

pub fn raw_handle(&self) -> zx_handle_t

Return the handle’s integer value.

pub fn into_raw(self) -> zx_handle_t

Return the raw handle’s integer value without closing it when self is dropped.

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

Wraps the zx_handle_duplicate syscall.

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

Wraps the zx_handle_replace syscall.

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

Wraps the zx_object_signal syscall.

pub fn wait_one( &self, signals: Signals, deadline: MonotonicInstant, ) -> WaitResult

Wraps the zx_object_wait_one syscall.

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

Wraps the zx_object_wait_async syscall.

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

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

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

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

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

Wraps the zx_object_get_info syscall for the ZX_INFO_HANDLE_BASIC topic.

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

Wraps the zx_object_get_info syscall for the ZX_INFO_HANDLE_COUNT topic.

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

Returns the [Koid] for the object referred to by this handle.

impl Port

pub fn create() -> Self

Create an IO port, allowing IO packets to be read and enqueued.

Wraps the zx_port_create syscall.

Panics

If the kernel reports no memory available to create a port or the process’ job policy denies port creation.

pub fn create_with_opts(opts: PortOptions) -> Self

pub fn queue(&self, packet: &Packet) -> Result<(), Status>

Attempt to queue a user packet to the IO port.

Wraps the zx_port_queue syscall.

pub fn wait(&self, deadline: MonotonicInstant) -> Result<Packet, Status>

Wait for a packet to arrive on a (V2) port.

Wraps the zx_port_wait syscall.

pub fn cancel(&self, key: u64) -> Result<(), Status>

Cancel pending wait_async calls for a given key.

Wraps the zx_port_cancel_key syscall.

Trait Implementations

impl AsHandleRef for Port

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

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

impl Debug for Port

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

Formats the value using the given formatter.

impl From<NullableHandle> for Port

fn from(handle: NullableHandle) -> Self

Converts to this type from the input type.

impl From<Port> for NullableHandle

fn from(x: Port) -> NullableHandle

Converts to this type from the input type.

impl HandleBased for Port

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

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

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

Create a replacement for a handle, possibly reducing the rights available. This invalidates the original handle. Wraps the zx_handle_replace syscall.

fn into_handle(self) -> NullableHandle

Converts the value into its inner handle.

fn into_raw(self) -> zx_handle_t

Converts the handle into it’s raw representation.

fn from_handle(handle: NullableHandle) -> Self

Creates an instance of this type from a handle.

fn into_handle_based<H: HandleBased>(self) -> H

Creates an instance of another handle-based type from this value’s inner handle.

fn from_handle_based<H: HandleBased>(h: H) -> Self

Creates an instance of this type from the inner handle of another handle-based type.

fn is_invalid_handle(&self) -> bool

impl Hash for Port

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 Ord for Port

fn cmp(&self, other: &Port) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Port

fn eq(&self, other: &Port) -> 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.

impl PartialOrd for Port

fn partial_cmp(&self, other: &Port) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
