Struct r3::kernel::semaphore::SemaphoreRef

pub struct SemaphoreRef<'a, System>(_, _)
where
    System: KernelSemaphore;

Represents a single borrowed semaphore in a system.

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

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

Implementations

impl<System> SemaphoreRef<'static, System>where
    System: KernelSemaphore,

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

Construct a SemaphoreDefiner to define a semaphore in a configuration function.

Trait Implementations

impl<System> Clone for SemaphoreRef<'_, System>where
    System: KernelSemaphore,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<System> Debug for SemaphoreRef<'_, System>where
    System: KernelSemaphore,

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

Formats the value using the given formatter.

impl<System> Hash for SemaphoreRef<'_, System>where
    System: KernelSemaphore,

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<Semaphore<System>> for SemaphoreRef<'_, System>where
    System: NotSupportedYet,

fn eq(&self, other: &Semaphore<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<SemaphoreRef<'_, System>> for Semaphore<System>where
    System: NotSupportedYet,

fn eq(&self, other: &SemaphoreRef<'_, 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<SemaphoreRef<'_, System>> for SemaphoreRef<'_, System>where
    System: KernelSemaphore,

fn eq(&self, other: &SemaphoreRef<'_, 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> SemaphoreHandle for SemaphoreRef<'_, System>where
    System: KernelSemaphore,

type System = System

The system type this object pertains to.

const unsafe fn from_id(
    id: <System as KernelSemaphore>::RawSemaphoreId
) -> SemaphoreRef<'_, System>

Construct a Semaphore from RawSemaphoreId.

const fn id(&self) -> <System as KernelSemaphore>::RawSemaphoreId

Get the raw RawSemaphoreId value representing this object.

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

Borrow self as SemaphoreRef.

impl<System> Copy for SemaphoreRef<'_, System>where
    System: KernelSemaphore,

impl<System> Eq for SemaphoreRef<'_, System>where
    System: KernelSemaphore,
