Struct r3_core::kernel::event_group::EventGroupRef

#[repr(transparent)]
pub struct EventGroupRef<'a, 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: KernelEventGroup> EventGroupRef<'static, System>

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

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

Trait Implementations

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

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

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

type System = System

The system type this object pertains to.

const unsafe fn from_id(
    id: <System as KernelEventGroup>::RawEventGroupId
) -> Self

Construct a EventGroup from RawEventGroupId.

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

Get the raw RawEventGroupId value representing this object.

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

Borrow self as EventGroupRef.

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

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

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

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

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