Struct RetiredSet

pub struct RetiredSet<'s> {
    hazards: &'s HazardBag,
    inner: Vec<(*mut (), unsafe fn(*mut ()))>,
    _marker: PhantomData<*const ()>,
}

Thread-local list of retired pointers.

Fields

hazards: &'s HazardBag

inner: Vec<(*mut (), unsafe fn(*mut ()))>

The first element of the pair is the machine representation of the pointer and the second is the function pointer to free::<T> where T is the type of the object.

_marker: PhantomData<*const ()>

Implementations

impl<'s> RetiredSet<'s>

const THRESHOLD: usize = 64usize

The max length of retired pointer list. collect is triggered when THRESHOLD pointers are retired.

pub fn new(hazards: &'s HazardBag) -> Self

Create a new retired pointer list protected by the given HazardBag.

pub unsafe fn retire<T>(&mut self, pointer: *mut T)

Retires a pointer.

Safety

• pointer must be removed from shared memory before calling this function, and must be valid.
• The same pointer should only be retired once.

Note

T: Send is not required because the retired pointers are not sent to other threads.

pub fn collect(&mut self)

Free the pointers that are retired by the current thread and not protected by any other threads.

Trait Implementations

impl<'s> Debug for RetiredSet<'s>

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

Formats the value using the given formatter.

impl Default for RetiredSet<'static>

fn default() -> Self

Returns the “default value” for a type.

impl Drop for RetiredSet<'_>

fn drop(&mut self)

Executes the destructor for this type.
