Struct RcuPtrRef 

pub struct RcuPtrRef<'a, T> { /* private fields */ }

A pointer to an object managed by the RCU state machine.

This pointer is valid for reading until the RcuReadScope is dropped.

Implementations

impl<'a, T> RcuPtrRef<'a, T>

pub unsafe fn new(_scope: &'a RcuReadScope, ptr: *const T) -> Self

Create a new RcuPtrRef from a pointer and a scope.

Safety

The pointer must be valid for reading until the RcuReadScope is dropped.

pub fn null() -> Self

Create a null RcuPtrRef.

pub fn is_null(&self) -> bool

Check if the pointer is null.

pub fn from_ref(object: &'a T) -> Self

Create a new RcuPtrRef from a reference.

pub fn as_ref(&self) -> Option<&'a T>

Get a reference to the object.

Returns None if the pointer is null.

pub fn as_ptr(&self) -> *const T

Get the raw pointer to the object.

pub fn as_mut_ptr(&self) -> *mut T

Get the raw mutable pointer to the object.

pub unsafe fn add_byte_offset<U>(&self, offset: usize) -> RcuPtrRef<'a, U>

Adds a byte offset to the pointer.

Safety

The caller must ensure that the offset is within the bounds of the object and points to a valid object of type U.

pub unsafe fn sub_byte_offset<U>(&self, offset: usize) -> RcuPtrRef<'a, U>

Subtracts a byte offset from the pointer.

Safety

The caller must ensure that the offset is within the bounds of the object and points to a valid object of type U.

Trait Implementations

impl<'a, T> Clone for RcuPtrRef<'a, T>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
