Struct Link 

pub struct Link<T>(/* private fields */);

Intrusive next-pointer field for UnboundedQueue<T> nodes.

Embed this as a field in T and implement Linked (which only needs to project to that field) instead of open-coding all four Node accessors. Centralizes the AtomicPtr storage so node types no longer need addr_of_mut!/AtomicPtr::from_ptr casts over a plain *mut T field.

#[repr(transparent)] so it has the same layout as the ?*T it ports.

Implementations

impl<T> Link<T>

pub const fn new() -> Self

pub fn is_null(&self) -> bool

Relaxed null check — for debug assertions only (the queue itself never reads through Link outside the Node accessors).

pub fn clear(&self)

Reset to null with Relaxed ordering — used when re-queueing a popped node so a stale link is not observed by the next push’s debug walk.

Trait Implementations

impl<T> Default for Link<T>

fn default() -> Self

Returns the “default value” for a type.
