Struct fuchsia_zircon::EventPair
source · pub struct EventPair(/* private fields */);
Expand description
An object representing a Zircon event_pair
As essentially a subtype of Handle
, it can be freely interconverted.
Implementations§
source§impl EventPair
impl EventPair
sourcepub fn create() -> (Self, Self)
pub fn create() -> (Self, Self)
Create an event pair, a pair of objects which can signal each other. Wraps the zx_eventpair_create syscall.
§Panics
If the kernel reports no available memory to create an event pair or the process’ job policy disallows EventPair creation.
Trait Implementations§
source§impl AsHandleRef for EventPair
impl AsHandleRef for EventPair
source§fn as_handle_ref(&self) -> HandleRef<'_>
fn as_handle_ref(&self) -> HandleRef<'_>
Get a reference to the handle. One important use of such a reference is
for
object_wait_many
.source§fn raw_handle(&self) -> zx_handle_t
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>
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: MonotonicTime,
) -> Result<Signals, Status>
fn wait_handle( &self, signals: Signals, deadline: MonotonicTime, ) -> 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>
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>
fn get_name(&self) -> Result<Name, Status>
Get the Property::NAME property for this object. Read more
source§fn set_name(&self, name: &Name) -> Result<(), Status>
fn set_name(&self, name: &Name) -> Result<(), Status>
Set the Property::NAME property for this object. Read more
source§fn basic_info(&self) -> Result<HandleBasicInfo, Status>
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>
fn count_info(&self) -> Result<HandleCountInfo, Status>
Wraps the
zx_object_get_info
syscall for the ZX_INFO_HANDLE_COUNT topic.
source§impl HandleBased for EventPair
impl HandleBased for EventPair
source§fn duplicate_handle(&self, rights: Rights) -> Result<Self, Status>
fn duplicate_handle(&self, rights: Rights) -> Result<Self, Status>
Duplicate a handle, possibly reducing the rights available. Wraps the
zx_handle_duplicate
syscall.
source§fn replace_handle(self, rights: Rights) -> Result<Self, Status>
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.
source§fn into_handle(self) -> Handle
fn into_handle(self) -> Handle
Converts the value into its inner handle. Read more
source§fn into_raw(self) -> zx_handle_t
fn into_raw(self) -> zx_handle_t
Converts the handle into it’s raw representation. Read more
source§fn from_handle(handle: Handle) -> Self
fn from_handle(handle: Handle) -> Self
Creates an instance of this type from a handle. Read more
source§fn into_handle_based<H: HandleBased>(self) -> H
fn into_handle_based<H: HandleBased>(self) -> H
Creates an instance of another handle-based type from this value’s inner handle.
source§fn from_handle_based<H: HandleBased>(h: H) -> Self
fn from_handle_based<H: HandleBased>(h: H) -> Self
Creates an instance of this type from the inner handle of another
handle-based type.

1.0.0 · source§fn le(&self, other: &Rhs) -> bool
fn le(&self, other: &Rhs) -> bool
This method tests less than or equal to (for

) and is used by the <=
operator. Read moresource§impl Peered for EventPair

&self,
clear_mask: Signals,
set_mask: Signals,
) -> Result<(), Status>
fn signal_peer( &self, clear_mask: Signals, set_mask: Signals, ) -> Result<(), Status>
Set and clear userspace-accessible signal bits on the object’s peer. Wraps the
zx_object_signal_peer syscall.
