Struct r3::kernel::event_group::EventGroupRef

pub struct EventGroupRef<'a, System>(_, _)
where
         System: KernelEventGroup;

Represents a single borrowed event group in a system.

This type is ABI-compatible with System::RawEventGroupId. It’s logically equivalent to &'a EventGroup but instead stores RawEventGroupId directly.

See EventGroup for the owned counterpart and the description of this kernel object. See EventGroupMethods for the operations provided by this handle type.

Implementations

impl<System> EventGroupRef<'static, System>where System: KernelEventGroup,

pub const fn define() -> EventGroupDefiner<System>

Construct a EventGroupDefiner to define an event group in a configuration function.

Trait Implementations

impl<System> Clone for EventGroupRef<'_, System>where System: KernelEventGroup,

fn clone(&self) -> EventGroupRef<'_, System>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<System> Debug for EventGroupRef<'_, System>where System: KernelEventGroup,

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

Formats the value using the given formatter.

impl<System> EventGroupHandle for EventGroupRef<'_, System>where System: KernelEventGroup,

type System = System

The system type this object pertains to.

const unsafe fn from_id( id: <System as KernelEventGroup>::RawEventGroupId ) -> EventGroupRef<'_, System>

Construct a EventGroup from RawEventGroupId.

const fn id(&self) -> <System as KernelEventGroup>::RawEventGroupId

Get the raw RawEventGroupId value representing this object.

const fn borrow( &self ) -> EventGroupRef<'_, <EventGroupRef<'_, System> as EventGroupHandle>::System>

Borrow self as EventGroupRef.

impl<System> Hash for EventGroupRef<'_, System>where System: KernelEventGroup,

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

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<System> PartialEq<EventGroup<System>> for EventGroupRef<'_, System>where System: NotSupportedYet,

fn eq(&self, other: &EventGroup<System>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<System> PartialEq<EventGroupRef<'_, System>> for EventGroup<System>where System: NotSupportedYet,

fn eq(&self, other: &EventGroupRef<'_, System>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<System> PartialEq<EventGroupRef<'_, System>> for EventGroupRef<'_, System>where System: KernelEventGroup,

fn eq(&self, other: &EventGroupRef<'_, System>) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
