Struct AtomicPolymorphicValue 

pub struct AtomicPolymorphicValue { /* private fields */ }

Atomic polymorphic value for concurrent access

Supports lock-free reads and compare-and-swap updates for inline values. Heap values require external synchronization.

Implementations

impl AtomicPolymorphicValue

pub fn null() -> Self

Create a null atomic value

pub fn from_inline(v: &PolymorphicValue) -> Option<Self>

Create from a polymorphic value (must be inline)

pub fn load(&self, order: Ordering) -> u64

Load the current value

pub fn store(&self, value: &PolymorphicValue, order: Ordering)

Store a new value

pub fn compare_exchange( &self, current: &PolymorphicValue, new: &PolymorphicValue, success: Ordering, failure: Ordering, ) -> Result<u64, u64>

Compare and swap

pub fn tag(&self) -> ValueTag

Get the tag

pub fn try_as_int(&self, order: Ordering) -> Option<i64>

Try to get as integer (lock-free)

pub fn fetch_add(&self, delta: i64, order: Ordering) -> Option<i64>

Atomic increment (for integer values)
